I am one of four RAs in my building. Out of the four of us, I am always the only one around when someone needs a lockout key. At 4 AM one morning, someone knocked on my window (I live on the first floor). Most people know that I don’t like them to knock on my window. Startled, I grabbed my keys and headed out into the foyer.
Some guy was running around outside, saw me, and then ran indoors. I asked him why he knocked on my window. “I forgot my keys,” he said. “Why would you knock on my window?” I muttered. “Uh, I needed to get inside.” He ran upstairs. I went back to my room, confused.
The next night, I was just about to go to bed when a heard another knock on my window. Furious, I ran from my room to the foyer again. Same guy. “I got locked out again,” he said. “NEVER knock on my window again,” I said. And he ran upstairs.
I haven’t seen him since.
