One day I waited for the perp. I was standing next to the washers facing the door when he walked in. He looked scared to see me, not that it should be uncommon to find someone else in the laundry room. He left immediately; walked in, peeked in, walked out. When he came back he went and got his laundry out of the dryer. I watched him without saying a word. He refused to make eye contact. I walked out with him and watched him walk home.
I let him watch me watch him.
Someone else has drama laundry woes too:
I have written "you're welcome" over her note.
