I AM NOT MANSTRUATING!
It's not "leaving," it's getting bored and not showing up for a while, or getting pissed off and walking away until one is no longer pissed off.
EDIT: BTW, Psy, you're an oldbie whether you like it or not on account of the fact that you've changed significantly since joining. There was a time when your screenname was condign.
EDIT2: Wait, Kyle is an oldbie? Who the deuce is Kyle?
