Do you do anything you wouldn't normally tell anyone in a normal conversation

I have brushed my teeth in the shower before but I hate the warm water in my mouth so I don't do it often. I'm trying to think of anything that may seem that strange to other people..... I never ever close my curtains ever when I am getting dressed in my room. Is that strange? I am not a exhibitionest or anything but it is something I am too lazy to do. How's that? Give me a clue to something else.
