I sit on my face... Oh wait...
OT: If it's on the floor, on my knees until I collapse face-first into the floor... Then, I lay there until I realize I have to get up something to go to the bathroom or something like that...
If I'm in a chair or something akin to that, then it's either with legs spread because I'm a "dude", "Criss Cross Applesause"[footnote]"Spider crawling down your neck
Stab
Blood trickling down your leg"
*blinks* ...what was I talking about again?[/footnote] if I want my legs to remind me of DNA, or with my right or left leg over the other like I'm some kind of anti-villian, waiting to smoke his candy cigar and laugh like as if he has a plan to get revenge on that one boss in a video game...
In general, I really don't pay attention to it, in general, until either my leg and/or my feet fall asleep or something...
