What are some odd things you do when you are alone?

We all do strange things when there are no witnesses around. What is it that you do?

I find that when I am cooking something new, I speak in funny accents to the food. It makes the cooking so much more fun and I tend to enjoy the meal more after. I also used to sing to my dog when my mom wasn’t home. He seemed to particularly enjoy when I sang Motown to him. Naturally, both of these are things I avoid when other people are around.

How about you, collective, how are you weird when you are alone?
