Yes. That's precisely the number. I do not believe in any science (or ad-hoc methods) that co-relate a number with personality. Still it is interesting to see the number coming back, again and again. Here are some of the facts involving 13 and me :
I was born on Friday, the thirteenth.
In my first adventure in this competitive world, I grabbed rank 13 in the divisional board, in the SSC examination.
My telephone number has two 13's in it : 4+3+6 = 13 and 4+9=13, make up my "43649".
My room number has a thirteen attached to it : T 76!
Today I found my blog ranked at number "283" amongst the fellow indian bloggers.
I guess, in the end there will be thirteen such facts before the spell breaks!
