This is gonna sound silly but, I never sit in chairs normally unless I'm being watched. I've presently got one leg folded under me, and the other tucked up, so I'm not sitting on my ass, I'm sitting on a shin and a foot. And I will probably move in a couple minutes. Is that the same as "Sitting on one's ass", or..?
