Must be oung is correct! Things were handled a bit different in the old days.....and better. ‘Personal responsibility’ is lost on the children now a days stylin.
A proven method of handling an jerk is to use the element of surprise, “depants” him and then attack. Make it public and it will humiliate him to the point he will avoid you.
What’s sad, though, is that the “old days” I’m referring to are the early seventies.
