Almost everywhere I go lately I see people picking their teeth of I assume plaque/food and sometimes flicking it away from them. Even when they don't flick it these people push elevator buttons I push, type on computer keyboards I use, and push doors I push. Where did this come from? It's like picking your teeth in public with your bare hands in the latest trend. In fact, I am in a computer lab on campus sitting next to some mofo picking his teeth as I type this -- seriously. This is gross and it must stop. Do people realize...
