Last night I couldn't get into my room. The key wasn't working for some reason- it would go in and just not turn. I spent about a minute shuffling the key, trying to get it to work. I knew someone was up because I heard water running in the bathroom. Right as I was about to knock, I realized I was at the wrong room.
Thankfully, no one seemed to notice the doorknob rustling, and I ran down the hall as fast as I could and prayed that no one would know it was me.
