When I went to college and lived in the dorms, we frequently dealt with random acts of "general college stupidity". Guys slamming doors at 3 in the morning, or dumping a trashcan in the lobby, coming in drunk and knocking on the wrong door. Some of it could even be labeled "offensive" by certain "ultra sensitive" parties.
We always just shrugged it off and said, "Hey, look what some idiot did." and went about our business.
