~I like chewing on ice. ~If I'm standing by a door in a public place, I'll most likely hold it open for someone.
~When on a line, if the person behind me complains to himself/herself that they are in a rush (or if they have way fewer items than me) I will let them go ahead of me.
~I'm a big fan of eye contact, so strangers often think I'm interested in them in one way or another.
~I can hummle - whistle and hum at the same time. People usually lean towards one or the other, if at all, and since I like both, I do both.
