Technically this will be my 3rd halloween. What did I do last 2 years? In 2009, I think I was in my apartment watching some TV episode on Hulu. In 2010, I was grading homeworks as a part of teaching assignment. I was invited for 2010 halloween party by some american friends. But I had no idea how to dress up for Halloween and somehow managed to convince them I was busy. Even after 2.5 years I don’t know how to dress up for Halloween or How to dress up for any damn occasion. Tshirt/Shorts for summer and Tshirt/jeans for winter sum up everything about my dressing. In 2011, my friend circle has extended so much so that in last few days I was bombarded with questions :”What are you dressing up as for Halloween?”"Have you bought your costume?”"What’s your plan for halloween, dude?” Some friends even took me to a store where people were buying Halloween costumes and accessories. Kids were having fun and I was wondering all the time what I was doing there. I bought Dracula teeth, thats all I could do to please my friends.
Over last few days, I was thinking how to tell people that I am not coming for Halloween party or I am not going to dress up as somebody. I would like to share some of these ideas.
Case 1: If you don’t want to attend Halloween party.
1. I shall be Higgs boson, nobody can see me at your party.
2. I shall come up as a superpartner (supersymmetric partner) of myself, unfortunately super partners are not observed yet.
3. I shall come to your party, but I’ll prefer to stay in extra dimensions.
4. (Lame) I shall be superluminal neutrino.
Case 2: If you don’t want to dress up for the party.
1. My costume belongs to Imaginary axis, thus it is purely imaginary.
2. I expanded my costume in Kaluza-Klein states, only zero mode survived.
3. I started up with a cool costume, but that was metastable so eventually I ended up in this stable costume.
There is no doubt that I would have loved this event thoroughly when I was a kid. In Graduate school, I just find it stupid. (Don’t mind if you have/had invited me for Halloween. By now, you probably know that I make fun of almost everything. 
)
you can dress up shabbily in the oldest set of clothes that you have..
if someone asks, “what are you?”..you say “i’m a graduate student”
or I can say “I am an IITian.” hahaha!
that you’ll always be irrespective of your costume..
financial condition changes once you graduate out of IIT..this doesnot hold true if you opt for grad school..
IITians scare the #$%# out of people by being simply obnoxious. hahaha!
haha, i can completely relate with such kind of things!!
