Before any number people go on about me advocating slugging everyone who looks at you crosswise when you have a kilt on....or saying "violence never solves anything".

1. I'm not advocating attempting to solve all problems by smacking anybody. Sathor ought to tell the guy to knock it off, that he doesn't appreciate the comments. Be direct and firm, but not a jerk about it. Do that several times, even. Then, tell him and be a jerk about it. After that, find ways to just not have to see the guy. Let his wife know that not only Sathor, but other members of the family don't appreciate his comments and attitude. If after many months of that, the guy doesn't get it, and still has to make "comments", then it seems reasonable to assume that his head is impermeable to information presented by anything less than a hammer, so use the hammer.

2. "violence doesn't solve anything". I disagree. In all my days I only did it once, and it was decades ago, but I laid a guy out for giving me untold grief for months on end, and son of a gun...he stopped giving me grief, and wow but the guy went on to be an upstanding citizen, hold jobs, raise kids and generally get on just fine in life. Seems like that 60 seconds around 1978 didn't ruin his life or unmake the world, you know?

It's a last resort, eh?

It seems kind of strange to be proud of our "Fighting Ancestors" and the non-stop Clan Feuding for a couple of hundred years....which sounds an awful lot like gang wars over turf to me...to put it bluntly... rather than high and might noble causes.... and yet pitch a fit over educating a jerk about his behavior by smacking him in the snotlocker.
