I've been taking a new shuttle route to work and the regular driver has sketched me out since my first ride. Something about drivers being too needy with conversation makes me crazy ... and a whole bunch of other things made me feel icky, too. But today sealed it. I was sitting directly behind him and glanced at his left hand. The thumbnail is about AN INCH LONG. That's crazy! I looked at the right hand, same thing, just the thumb. What is this about? Is there some medical condition that requires a person to keep their thumbnails long? What. Is. The. Deal.
