I left a comment saying, "Uh, news flash, you're PAST middle aged."
Later I asked him if he thought I was a dick for putting that.
Him: No, but you're wrong. I'm not middle aged yet because I'm going to live to be 85 or older.
Me: I don't want to live that long. I need to die before I turn 65.
Him: You don't want to meet your grandkids?
Me: Dude, I'll probably have grandkids in the next five years or so.
Him: Oh yeah. Well what about your great-grandkids? Don't you want to get to know them?
Me: Nah. Fuck those assholes.
