This one made me laugh. While it's not on the list of things never to say on patch day, it is on my list of things to never say if I want to get out of the office early or at a reasonable hour. Without fail, any time I tell the better half that I'm going to try to leave by X time, something ends up happening and I don't leave for several hours after that time.
I changed the list to add a note about you, since Kate seemed lonely at #5.
