Today when I went to get my bike from the bike shed at work on the way home, I noticed that it had been shifted from one side of its stall to the other. As soon as I got on, I noticed the right handgrip was tweaked to the side, and as soon as I shifted gears I noticed that the derailleur was wonky. I could still shift but the gears were all out of alignment.

It looks like somebody knocked my bike over at some point today, which scuffed up the right handgrip and bent the derailleur hanger. I'm annoyed because of careless people who knock over other people's bikes, and doubly annoyed because it's going to cost me a new derailleur hanger to fix this.
