Woman Friend of mine: I like that you’re my friend and visit me even though there’s no chance we’d ever have sex.

Me: No chance?

Friend: Why, are you interested?

Me: No. Sex is a lot of work at the best of times and I’m tired. I just wanna chill, really.

Friend: Then why do you care if there’s a chance or not?

Me: I like optionality! I don’t want to rule anything out.

Woman: Ok. There’s a trillionth of a trillionth percent chance.

Me: Ok, much better!

(This wasn’t confrontational. We’ve known each other quite a while and we were both joking around in a much longer conversation about how men and women relate and misunderstand one another.)
