I have no idea who that dude is. All I know is the girl got on the stop after mine and sat across from me. The dude got on the same stop as her, but came in a different door. As soon as he saw her he made a beeline for the seat next to her--where he took up 2/3 of the space, leaned over to see what she was working on, and then immediately threw his head back to sleep. WTF?
I've never seen this guy before, but he's asian and wore a big wool coat on top of a shirt and tie. My guess? CELLULAR PHONE SALESMAN.
