You won that argument in the shower twice this week. The other person has no idea.

Rehearsed arguments are satisfying because you write both sides and your side always wins. Nothing gets resolved by them. The whole exchange happens in a room the other person is not in, and you come out with your heart rate up and the conflict sitting exactly where it was. Meanwhile they have moved on, or never noticed.

If it is worth arguing about, have the real one, out loud, with the actual person, in fewer words than the shower version used. If it is not worth that, it is probably not worth the shower either.
