Well, maybe not, but habits or behavior. I'll be adding to this thread but at this very moment, I wonder about this one thing. Why do some people would lose their toothpaste cap and use the tube capless like that? Why?
Why?? Why???? It's messy and dirty looking. I have a house guest, and it's a woman. She's driving me nuts.

I'm not being too picky here. This is the least thing that annoys me. Actually, I'm just wondering, it's not bothering me too much. She does lots of other stuffs that bother me. I'm gonna finish clean up and go to bed. I'm feeling tired and unhappy tonight.
