Not saying what you are thinking = manners.

There are two way to deal with mudcat bickerers,

Manners = unilateral disarmament if the rules are not enforced

or

Slap them back with one's metaphorical dueling glove without engaging in the bickering.

the third way is to bicker back. But dude isn't listening to me. Dude is giving me zero benefit of the doubt. So I'll be phucked if I'll listen to him.
