Conversation on the Subway

MathGimp, I am the man at Starbucks who asks too much about your dairy habits.

Scene: 6 o'clock; Going home from work on the crowded subway.

Me (to the man sitting next to me): You're sitting awfully close to me, and I don't know how I feel about it.
Stranger Man (quite rightly taken aback that someone is speaking to him on the subway): Ummm..yeah it's as if we know each other...(nervous laugh)
Me (with an extravagant wave around the train): How many people on this train do you think are absolutely miserable? I mean, how many do you think are coming home from a job they hate?
Stranger Man: I'd guess a lot of them.
Me: Are you miserable at your job?
Stranger Man: Yeah, I guess I am pretty miserable there.
Me: Yeah, I think that's how it goes with most grown ups. But not for everyone.
Stranger Man: Who isn't miserable?
Me: The people who swim with dolphins for a living.
Stranger Man (trying to look at the bright side of things): Um, yeah. But if we didn't work at our miserable jobs, we couldn't live in this amazing [New York] city.
Me (Immediately finding the weakness in his argument): Yeah, but it wouldn't matter. If we swam with dolphins we'd live at Sea World.
