I've seen "Polite but not weak" in action - again, with my Dear Old Daddy. He'd give the offender a couple of chances to recant - even to the point of taking the first one on the chin - then pound him into the Earth like a tent stake, all the while asking "Have you had enough yet?" He grew up in the rough and tumble coalfields of Raleigh County in West Virginia, the son of the local moonshine distiller, Constable ..... and traveling lay preacher. I like to tell everyone that he was HUGE powder keg with a really long fuse. He claimed that he didn't like to fight, but he was darn good at it if you riled him past "polite". He taught me some of the same skills, although I did not inherit the upper body strength of a lowland gorilla or fists the size of tavern hams from doing work that would kill three "modern" men ..... That alone kept ME pretty well in line as a recalcitrant youth .... Hahaha!
