Hair

I really hate bus rides when somebody else is doing something that invades your space. Usually it's them coughing or the fact that they smell like pee, but lately for me it's been women (or men on occasion) with looooooong hair sitting on the seat in front of me, oblivious to the location and positioning of their hair, and I'm talking about hair long enough that's it's sitting in my lap and our touching my coffee.

Is there anything grosser than other people's nasty hair touching you on the bus?
