One of the downfalls that comes with taking transit everywhere is having to walk home from transit at the end of the day.
That's exactly what I was doing tonight after finishing (and hoping to forget about) my last final and celebrating with my classmates after. It was after midnight when I was walking home from the bus. I'm tired; I have my headphones in; I just want to be home and I'm not interested in talking to anyone. I'm waiting to cross the street when I think I hear someone in the lone car at the intersection say something to me. Now I'm tired and my brain is fried from finals, so at first I assume they must be lost (because why else do you strike up a conversation at a crosswalk at midnight) and it takes a few seconds for my inner skeptic to kick in. By the time I realize it's just a couple dudes in the car, not so much lost as pathetic and starved for attention, I've already made eye contact. They say something else I can't hear because...well, headphones, but I give them a wave (because thanks for not running me down with your car I guess) and carry on crossing the street...because what the heck else did they think I would do.
Then as I pass the car I hear the one guy say, "The least you could do is say hi." No, jackass, the least I could do is completely ignore you and pretend like your pathetic existence isn't ruining my perfectly peaceful walk home.
