No one is here by choice! Were it so easy to leave I would have returned home to take care of my own problems, not languished here under some misguided sense of responsibility!

[He goes silent abruptly, reigning in his annoyance. It's a waste to be angry with this stranger, he doesn't even know why he's letting it get to him. When he speaks again he just sounds resigned and very tired.]

Tell me your name, so that I know not to waste my time debating this with you again in the future.
