perhaps it is simply that my brain has nothing else to exert itself on, and so its amusing itself by playing through all the possibilities - had i turned left instead of right, said this instead of that, raised an eyebrow or laughed, what would have happened?
I hate these WhatIfs.
i had long ago convinced myself that such thoughts serve only to drive one mad (if i did this for every shot on the golf course i would probably have went off the deep end ages ago), but it doesn't help now. i guess the only solution is to work like mad for the entire day, so that there is no choice but to sleep out of exhaustion.
