I have my own room. It's actually the biggest bedroom in the house, and also the top floor of my house. I've never shared a room with anyone before, except during senior week. I shared the living room of the house we were staying in with another one of the guys who came along. Although, I don't really count that because the room didn't belong to us. So I've always had my own room.
I keep my room fairly tidy, but there's always a pile of clothes on the floor next to my dresser. I don't know why I haven't bothered to actually put the clothes away yet. xD But other than that, my room is tidy. My bed is usually a mess, though. All the other things I keep in my room, however-- video games, books, etc-- are usually pretty organized. I'm kind of anal about my stuff. That said, I always seem to misplace the remotes for my stereo and TV. xD
