” wonder if a restraining order could be filed.”
Not my style. Nor telling the father’s CO. Nor telling the school.
I’m of the mind to:
1. Confront the kid, possibly with the father’s permission;
2. My wife kind of knows the mother and could talk mom-to-mom;
3. I talk with the father; or
4. Do nothing but try to avoid the fat turd.
Mom to mom might be the best first option.
In that case I’d say talk to the father as well.
