When I'm the GM, I generally stay in one place. At one friend's house, that place was the big comfy overstuffed chair in the corner, because I could perch on the back or the armrest, or sit curled up in the middle of it with my notebook on my lap. At another friend's house, I claim a pillow in front of the fireplace, so I can roll dice on the coffee table and pile books next to me. Can't GM without all the tools right there, y'know.
But when I'm just a player, I'm all over the room. I stand up, I pace, I wander into the kitchen and back, I sit or lay down on the floor with a pillow, and do all my dice rolling on the back of a book laying on the floor.
Occasionally one of our regular GMs who is in the market for a house says that he's looking forward to having a big dining room table we can game at, and he looks pointedly at me when he says it. But it won't help, and he knows it; we played around an actual table in college, and I was still the guy who kept standing up and wandering around, or turning his chair at an odd angle and sitting in it sideways, or tilting precariously back against walls.
But then, my inability to sit in a chair like a normal person has become a running joke in our group. I'm just not any good at it. If I sit the way you're supposed to, it feels awkward and really uncomfortable.
