On the way back he started whining about "why can't we do it this way," we got in a nice verbal tussel, and I said "If you say one more f***in' thing about it, I'm driving all the way back right now." It was like 1am, with four hours to go. He had to say something else, and it wasn't a nice thing, so I drove all night.
The story isn't to illustrate how innocent and righteous I am, of course. Just that I don't like uninvited control.
