I would regret it as he is a good man, but I don't regret it because it was really funny and he is a good enough man to understand it was a joke.

Thete is the good man, and his sister's husband. The sister's husband loves telling the good man that he fucks the good man's sister and does it all the time.

We're playing a game and, during it, the sister's husband is complaining about ordering a new dishwasher and the delivery of the dishwasher keeps getting delayed. During the game, the sister's husband does something that screwed the good man over for the sister's husband's benefit.

The good man snapped and said "I hope your dishwasher never comes!"

I responded with "You really shouldn't say that about your sister."
