"Glasses"

Driving class is going great. Tests every week and I'm getting 90's and 100's.
Getting on the bus to class is where the action happens. I got on the bus and there is a hooded, youngish late teens, early twenties guy sitting in the front with bags all around him. He stares at people as they get on the bus. He gives me a look. A dude with suspenders and huge Erkel glasses gets on and sits across from the guy with the bags. The guy stares at the dude with the glasses with annoyance and exasperation. He mutters, "glasses" and "bald headed". The dude looks uncomfortable but doesn't look at the guy who is obviously talking about him.
The homeless guy looks at me and sticks out his tongue. Not like in a nasty way, but like a first grader nya -nyaing his friend. I laughed out loud, it was so funny, such a strange gesture from a stranger. I did not stick my tongue out at him.
