I’ve recently noticed a weird little habit of mine. Appearantly, I am unable to use a urinal without first spitting into it. Why do I do this?
What do you do that you can’t explain.
Maybe someone else can explain it.
Whenever I turn on a sink, I do that too. And my wife thinks I’m nuts because in my shower we have sliding glass doors, and I go in the one closest to the shower head, and I go out the furthest door. I don’t know why I do that, it just doesn’t feel right going in the “out” door.
I think you are both nuts. 
If I feel any “residue” on my hands, or a foreign smell, I have to wash my hands as soon as possible. It’s one of my compulsive habits.
