So I was about to leave for work early this morning when I noticed that one of my neighbors had locked their bike such that I couldn't get mine out (like literally, I spent a good 10-15 min trying to get it out). I was in a hurry and frustrated so I went back up to my apartment and wrote a quick note along the lines of: "Hey, please don't do this again or I'll get the supers to cut your lock. But for today, I'll just return the favor and keep your bike in place too. I'll be unlocking it this evening at 7 PM."
I then went back down, taped the note to the seat and locked our bikes together. My commute was a 30 min walk. I got to work late. Finally, I come back home and go to unlock the bikes. My tires are slashed. Like seriously? What do I do now? I live in a large building so I don't even know the owner of this bike. I'm probably going to talk to the superintendent but am also considering leaving my number on the bike so we can talk this out. But who's the asshole here?
