If you’re compensated for your time and your training - I have no issue with it. I am bothered when someone comes out and says, “your prior training is useless”, and then charges you an arm and a leg. Seen it too often with scammers.
Agreed.
On a separate note regarding the violent youngster in question,
I would submit that if the parents of this boy’s schoolmates
are not concerned then they should be. If the kid is bold enough
at 6 to assault a large adult he would have no problem forcing
his will on his peers. I have seen countless SED little guys get
angry enough to take-on much, much bigger kids w/out hesi-
tation. Taking on adults is another story.
