I sing along with the music in stores. Sometimes I dance too. I don't realize I'm doing it until someone looks at me funny. That doesn't stop me, I just become aware of it.

I put my knee on the counter when washing dishes. (I'm tall)

Like an above poster I also say sorry for everything. Definitely a Canadian thing.

I also.....am embarrassed about this, flip people the bird when they are jerks while driving. I so don't mean to. It just happens.
