'Sense' of humour

Another morning when I drag myself out of bed and in a half asleep condition, I (as usual) promise myself to do some constructive work today and so far, i have already wasted an hour doing nothing. Here I am writing a blog again even when i put my first blog like yesterday :P (in ideal conditions people put their posts after a significant time gap...you know that way every blog looks important and the writer gives an impression how busy he or she was. Result: better impression.)
I am an Indian who has perpetually lived on nescafe' forever and here i am in firang land where infinite brands of coffee confuse me and make me wonder whats the importance of coffee in my life! Till the time i was at home, coffee was more of an additive to make the milk taste drinkable or when we would run out of bournvita supply and mom still had to make us gulp down a never ending glass of milk. But then lightening struck and 'cafe coffee days' revolutionised india.
Its at that moment (while trying to fix myself a coffee) i remember that i had forgotten to brush my teeth...and its then while being engrossed in the activity of brushing my teeth that the great thought took birth in my usually useless brain. Brushing lazily and looking at myself in the mirror I wondered (apart from also thinking how messy my hair were, what kind of hair serum must i apply, why am i wearing glasses while brushing my teeth... blah blah blah) so I wondered, how would you define the term 'sense of humour'.
Ok now since it is called a 'sense' of humour, it gotta be something serious... since the words like 'sensible', 'sensitive', 'senses' etc all have a very serious connotation attached to them, so how serious can humour be.?? Well i know for sure that it is an important characteristic trait (women want a man with a good sense of humour, often people are described as having a sense of humour.. etc etc. Maybe it has a subjective definition depending on whether you like the person or not, whether the guy is good looking or not, it just might be directly proportional to the degree of 'cuteness'... and yes, then I also want to know, how would PJ's be categorized ????

I fall into that category of 'pj' (poor jokes) cracking people. Whenever i say something, i, in most cases, find it so funny and laugh so much on it that the person in front cant even understand my words let alone the meaning of what i was trying to say. And then forever i get that ' Its NOT FUNNY' expression!!!! Infact my boyfriend laughs on the fact that my jokes are not funny!

The chain of my arbitrary thoughts end when my house mate knocks at the door making me realise that i have spent ages on the brushing activity. And when i step out of the bathroom, since my mate looks quite annoyed, I willingly make an effort to 'crack' a joke (crack..whoa! what a word..you crack CAT and IIt entrances, not jokes!) and i receive the age old expression "oh no not again" kinds....well, thats a biologically programmed 'defense mechanism' that people around me adopt to safeguard themselves from the potential danger of my jokes.
