What's the grossest habit you've ever picked up, seen a friend or someone on the street do? How about a family member? Does someone eat their fingernails or do something ridiculously disgusting? I've seen a friend's Mom pick her skin non stop for days on end, and it was pretty gross. What's the grossest habit you've encountered with someone?
