Inappopropriate bus behavior

Some of you may be aware that people clipping their nails on the T is one of my pet peeves. Today I witnessed a new transportation faux pas: a girl on the bus TWEEZING HER EYEBROWS. She was using a little hand held mirror and plucking away with a pair of tweezers. What if the bus had stopped short and she poked her eye out? That would have ruined my entire weekend, considering I have a major eye injury phobia. Save it for the bathroom mirror, missy. Public transportation is no place for personal grooming, people!
