I have a lot of shit.
It's starting to get a little sad in my apartment, now that I've started taking down the wall hangings. You know, it took me almost a year to decorate. I moved mid-1L and couldn't be bothered fishing out the hammer and nails, until my friend came over sometime during the summer and ranted about how much my white walls depressed her. Since then I've accumulated tons of photos and "art," including three fantastic white antiqued shelves I bought and installed myself. That's going to be fun to re-do in my new bedroom.
Also, a tip from me to you: Don't nail anything through wallpaper in your rented apartment. You will regret it when it comes time to move.
