There is no "T" in "drunk"

I don't know what it is about drunk dudes on the T at night. I usually can't tell if they're even with anyone because of the crap they say to any woman within earshot. So I'm on the train with my friend, who's pretty tough but seems like an average woman if you just glance at her. It's probably 11pm, and we're riding home from a concert. Enter drunk dude and woman he's trying to romance. He's talking about currency, like how five quarters equal a dollar-twenty five or something, and suddenly he's talking to my friend. And because he's wasted and apparently not with the other girl (who might otherwise keep him in line...though you never know, I guess), he will NOT leave my gal pal alone. I'd never seen this before from her, but instead of reacting, she just stared straight ahead. Like this amazing blank stare that made me want to crack up because at first, the guy didn't seem to notice. Then, he got mad because my friend was obviously ignoring him. He made a comment about people from New York (what?!) and tried his luck with the other woman again until they got off the train. Meanwhile, my friend suddenly struck up a meaningless front conversation with me, and we pretended to talk while I managed to hold it together until they left. Once they were gone, I cracked up. And she sighed. The sigh was because this happens every single day. And she knows it.
