Journal (2011-Jan-18) Physics Exam

18 January 2011

I was awake whole night. I had to cover syllabus for making it for four units and also to make it sure I revise the read topics once. I reached college and sat on the staircases of that building once again.
There were MAIT students dressed in suits coming up with file-folder in their hands in cars. I learned they had job-interview and test for the same. I wondered about my college, NIEC (ADGITM) and wondered about my own future. Nah, I am not running for any job but it’s good if it’s coming.

Faizan came by and we revised for some time together. I wanted to go to toilet but I didn’t. I was feeling sick of hangover from last night, but I didn’t show up. The teacher didn’t allow me to go to toilet once he had given me the answer sheet. I didn’t bother to go later, waste of time.

(Earthquake was felt just now, 0200 19 January 2011. I was sitting and my head starts shaking. I thought if I am getting shocks in head. Then I lifted my head from the laptop screen and found that fan was oscillating. I was terrified for a moment and I muted the laptop and sat dreaming about the next. Next was nothing. In a minute, the building was back to stable. There was noise of a woman from outside and I went out in the balcony for a second. So, the earthquake was confirmed.)

I found the exam to be too lengthy. I missed the Unit 4. I missed a Unit 3 numerical, and I knew how to do them. Oh god, I am in loose condition again. I need 35 and I attempted paper of 48 marks. So I am feeling neither good, nor bad. I am just not feeling okay as well.

After exam, I went to NIEC (now ADGITM) to issue book for next exam. I was accompanied by Kirti Mohan. Uh, while sitting in three-wheeler I tore a little stitch next to the side-pockets. It made me feel bad for hours. My mood was already down because of physics paper and now this blow to my mental being was intolerable. I kept going and doing my things quietly though.
I only felt relief when amma told me that she could stitch the cut back.

In the afternoon buaji was here to take kids back home, and I found her a little too happy in making a verbal connection with me. There surely must be some reason but I don’t want to know. That’s because sooner, or later, the things will change.

I was sleeping from 1700 to ten-thirty. I was thinking about all that happened during the day. At the metro station (Rithala), I was emptying my pockets into my bag and I saw that Kanika Sahni stood straight in my line of sight ahead at a distance. Well, I was looking for Faizan and Neha who were about to come. But then I saw this pretty lady. And I guess I caught her eye because she was looking here. Then she moved behind that person (one of her classmate) with whom she was talking. That was direct indication of the fact that she had noticed me for at least once, but I couldn’t understand for hours what that show of baseless confidence was for? She has a looks very strikingly similar to Anshu ma’am who in turn looks a copy of another Bollywood actor, Anushka Sharma.

Journal (2011-Jan-17) Preparation for exams

Index of Journals

January 17, 2011

I am again short of time. If I don’t revise all the topics done then it would be useless to even count them. It is 0003 right now, means the date has already changed, oh god!

Okay, I had been taking the subject lightly. During these preparatory leaves, I was going for walks, I was never dropping my music-phone away, and I was watching television shows, what else would happen on the day before exam?

Manju buaji was here in the afternoon. She came with babaji who had been to court in the new car, SX4. She kept saying about it. I had never touched pen and notebook for preparing for exam but tonight I will. 
This girl Anushka comes here and she is a mere waste of time, trust me. 

Oh god, one chapter still left...

Journal (2011-Jan-16) Aunt's new phone and uncle left

Index of Journals

January 16, 2011

Yesterday, in the park where I go for walk, I was met by this person Anil Yadav. I didn’t want to talk but then chose not act awkward to shoo him away. What interested me in him was that he was doing some management course from NIIT and was also preparing for MBA entrance tests. Nothing else, it was the first time that I talked to anybody there. Otherwise, he was just another outsider in Delhi. He was again from U.P., Agra.

Yesterday in the morning, Anushka and Prashant together in the room and when Anushka was toying with my phone (caring nothing about its, Sony Ericsson w350i, flap) Prxnt was interestingly watching when the wrong would happen. I had to shout at Anushka to get my phone back and I didn’t mind being very harsh and rude to her. I was actually mad at Prashant’s act though.

Last night, chachi-chacha and Srishti went to get a new phone for chachi. It was very irritating to hear Srishti asking for phone worth R10000 in the evening before they left. But then chachaji must have told her some story to shut her up.


Today chachaji left. Though amma had called me to come out but I didn’t. That’s because neither I wanted to, nor chachaji would have mind.

Journal (2011-Jan-15) Brilliant Tutorial Bills

Index of Journals

January 15, 2011

I just threw the bills piled up in my drawer for some time now (earlier amma had them). The bill of admission-cum-scholarship test, the bill of payment made as fees at Brilliant Tutorials. ‘Rs 500 as for test on 29th April 2008’ and ‘Rs 37068 as year-long tuition fees on 3rd May 2008’ read the bills. Amma always said fifty-thousand to put burden on me. But it was not. I got the scholarship of Rs 10000 and babaji had got another 3000 reduced by showing the papers of (Babbu) dad’s no-income at the office.
It used to feel bad, but now it doesn’t. Now, it is like ‘how is it wrong?’

Lately, I was happy to see that Achal Kaushik accepted my friend request after almost a year. It will help me put down past moments better. I made a separate Facebook profile for such contacts from my past, keeping in mind that I don’t connect to them or let them join me on my profile for current college (NIEC / ADGITM) friends.

Journal (2011-Jan-14) Grandpa's health

Index of Journals

14 January 2011

Babaji’s ill health... Chachaji’s new avatar... Chachiji is bad as ever... Physics exam is four days far...

“What problem do chachiji have if heater remains on for a couple more minutes in babaji’s room?”
“What problem does she have with me warming hands before it (though I never did it, but I know her problem by the look of her ugly face)?”
“I remember from previous months, she used to take iron-machine to her room when I would be in amma’s room early in the morning... This woman is totally sick!”
“It’s irritating to always find her peeking from the sleek space left between closed door of amma’s room...”

“Chachaji is acting like he holds no grudge against me and it’s just me who is holding the grudge now; looks like he is giving up on me but I am not slowing down for anyone.”

“I have seen babaji sleeping in his weak health and I wonder if he is breathing or not. It’s really awful to see him this weak in his sleep, it’s really awful.”

“Physics re-exam is on 18th, I had pretty much time but now I am again felling short of it. I was on internet till evening since 0200 last night and then I didn’t get over with the running-nose and cold because of irregular sleeping time. Plus, I had nightfall at six in the morning, so it left me tired through out the day.”

Journal (2011-Jan-13) Day of Lohri

Index of Journals

13 January 2011

It is Lohri today. Gurarchi had texted last night. 

Hardik’s call came just minutes before nine (2100). I had no plans to go out but then I did, and that is I. Yeah, he told me the stories of his recent life. It was politics going on in the society, his father’s ill health, Naina, and all that stuff. It was over-all fun to talk to him. In the end when he asked if we were meeting soon again, I said no. Of course, not, we discussed topics from months in mere an-hour-and-half, what would we talk if meet again in three days!

Sometimes I listen to those tracks of Eminem which I used to when I ended up Sonal’s chapter. And pass some time in the recollection of a sadly-ended-story of my one-sided love. Tracks in the playlist follow like this, Love the Way You Lie (by Rihanna ft. Eminem), 'Love the Way You Lie' (by Eminem ft. Rihanna), 'Space Bound', and ‘25 To Life.’ It was surprising when I thought I heard Sonal outside and rushed to the balcony door yesterday afternoon. I didn’t confirm if I was right or wrong.

Babaji is having a bad time with his health. He is struck by cold. We had to consult doctor for supervision. 

Buaji was here to collect Prachi and Anushka but I was in my room. So I didn’t see her. And anyways I didn’t want to either. Plus, this feeling is mutual between us.

And at the end the day I wish I could get out this house early as possible.

I over slept last night and that seem to be my birth habit.
I didn’t have a bath today and amma told me wash my under-garments on my own. When buaji was here in the afternoon, I got to hear from her on the same. She said it’s cheap.

I didn’t want to play with Anushka but she was irresistible when she got after me. Uh, I wanted to study but then I had to make her write alphabets on laptop and then play her games with her. Sleeping and waking up, sleeping and waking up!
I took the book after lunch at four and dropped at six-thirty to go for evening exercises.

Everyday I get to think about Sameer’s birthday I missed. It was on eighth Jan, though I was anyway not going to wish but then I just missed.

Another day, I started to study today. Yes, I was pretty much into studying after just eating and sleeping whole day long till four in the evening. 

It felt better to see Manju buaji. 

I went for walk at seven, thinking about what chachaji had said. If I score 70 percent, I would be eligible for applying for concession in the next year. I told him I would get 70 percent. He didn’t mean anything else this time, I guess.
Okay, amma got a call from Manju buaji today. And amma told chachiji not to say too much to Prachi about having breakfast here, and not at her home. Amma said it’s a matter for each day, in different forms. That’s not good, that’s just not acceptable to whom it is said. Amma had made Prashant a witness to this today and she, in his name, complained to chachiji of her unacceptable behavior. Chachaji intervened quite early. He had to. Chachiji then, after denying to any of the claims again and again, called out for Prashant. But chachaji didn’t let her do that. Anu slides her room’s door in the balcony and I put earphones in my ear to go offline.

After going to bed at 0500 in the morning, I woke up at 1200. Nothing as such happened during the day.
I was sleeping in the afternoon, woke up around six, and had dinner early. I picked up some thing related to study for the first time after seventh Jan. I checked previous years question papers for important-and-sufficient topics. 
At seven-thirty, I went for walk.
Now it’s ten and I will start some serious study.

9 January 2011, Sunday

I woke up early at 0800 and went to do exercise in the park behind the society. I got haircut today. It’s the same old Brad Pit Style from Mr. and Mrs. Smith. 

In the afternoon, I was watching this movie and chachiji came there to trouble in the last scene. But then the movie was “Pursuit of Happiness” and the story just didn’t push her to do that. 
Ha-ha, somebody put chewing gum inside the handle of the new SX4 of chachi’s and she thinks if I did that! 

Ankur was here at the same time. Well, he just surprised us. 
At the end of the day, I thought if he was here on someone else’s words. He was about on some second purpose. 
I was really into deep thoughts when he put his cold hand on my throat, and later in Prashant’s shirt. Then he was also asking me to get with him to Manju buaji’s house. I said a clear no. He asked a number of times but I had no plans to do that. Later, in the movie (which he left on laptop (now in my folder)) I saw totally naked scenes. It nearly drowned me into deep thoughts if there was something fishy.

In the evening, I was sending jokes to girls in my contacts. Some even replied. I had to waste 150 messages, there was no other way. I sent on even contacts which don’t know me. So a number called on phone a number of times. I was afraid to pick it up, but then it was just an equally scared man.

So, chachaji returned today. I didn’t mind. He was on wash-basin blowing his nose out, that’s when I heard him from inside my room.
Just watched “Golmaal 3,” it is 0500 right now.

Ten Suggestions (a lesson and a joke)


    
“I’ve got some good news... and I’ve got some bad news,” the lawgiver yells to them.
“Which do you want first?”

“The good news!” the hedonists reply.

“I got Him from fifteen commandments down to ten!”

“Hallelujah!” cries the unruly crowd. “And the bad?”

“Adultery is still in.”

- - -

The Hedonists think: Why should we be judged according to another’s rule?

And yet judged we are. 

After all, God didn’t give Moses “The Ten Suggestions,” he gave Commandments; and if I’m a free agent, my first reaction to a command might just be that nobody, not even God, tells me what to do. 

Even if it’s good for me.
