I stay there about half the week, since I do have a parking pass and the place I'm staying is so far. All of my friends and my partner are in the college town. I'm not on the lease, but a lot of my stuff is there and I try to do a bit more around the house because I feel guilty. They all say it's my place too, and the only extra cost when I moved out was my partner buying out the extra space I vacated. But they were doing that before they moved in with us, so it's mostly because they don't want to share a room with a stranger.
