I'm not saying that Terry is wrong in his decision to terminate this childs TKD involvement at his school. But without all the information, it seems a very harsh action.
I believe there is much more to this then is posted here.
It always looks harsh when it is in black and white print. And it is harsh for a child when the parent, who is supposed to be setting an example, is behaving in a childish manner which ultimately causes the child to suffer.
Generally, things like this go on for a goodly amount of time before coming to a head. Consider that an instructor spends the bulk of his or her time teaching. Interraction with the parents occurs only between classes and at the end of the day when classes are done, at which point, the staff is ready to go home.
When a parent or small clique of parents need to be babysat because they cannot behave themselves, the school staff is not to blame; they are busy doing what they are supposed to be doing: teaching class. Parents who need to be in some kind of adult daycare are not the responsibility of the dojo staff.
And as a parent, I cannot stand parents who behave that way. They take the instructor's time and attention away from the class, which is what I am paying for for my own kids, be it martial arts or a soccor clinic.
Unruly parents are a fact of nearly all school age sports programs, be it soccor, football, or karate class. Terry has what I consider a very large school, so it does not surprise me that he has a clique of them to deal with. Such parents often ruin things for their kids. Like dads who go charging onto the field to actually grab a kid on the other team. Or get into fistfights with other dads because they cannot control their tempers. There are certainly mom equivallents, who try to micromanage every move that an instructor makes because they have the answer to everything, never mind that mom has no background to do so.
And yes, it is harsh because the child suffers for a parent's immature behavior.
