nine and twenty

i always make it a point to be away, if possible, whenever my day comes. come to think of it, why indeed? is it because:
a) i avoid treating friends;
b) i can't accept the fact that i'm growing up a year older;
c) i want to celebrate it with just me, myself and i;
d) i dislike being the center of attention?
well... believe it or not, the answer is letter d. really!
