I got another dose of the apathy tonight; at least it wasn't aggression.
I was taking the last train home and a man got on. He was talking loudly and drinking a beer, so I put on my headphones so I could ignore him. A little while later I happened to glance up and noticed he was snorting coke off his house keys. Not that I really cared, but it demonstrated his mindset.
Not too long after that I smelled smoke. It was no real suprise to me who was smoking. I pointed out that it was a non-smoking train, to which he replied that he knew. I then asked him to quit smoking but he didn't, so I had to go call for the train personnel to deal with him. Then I moved to another part of the train.
Yet another nice evening out made less fun because of some jerk with no consideration for others... (Note that I don't think this describes all smokers, but I sure encounter a lot who are like that.)
