ETA: as the mom of a black belt and high red? I know it gets tougher and more is expected of you as you climb the ranks. Congratulate her on her hard work!!! My son - the black belt - needed a break as it did it for 5 years straight (it was afterschool for both of my boys for 3 years)...I told him once he achieved black belt - he could take a breather. It's been 3 years and now he wants to go back. He'll be able to wear his black belt - but they will have him start back with the no belts to make sure he has his forms right!
Sorry - there's something going on. My oldest son LOVED school - Kindergarten was a BLAST for him - was upset that there was no school on Saturday and Sunday....1st grade? hhhmm....first month was fine...second month?? I would get calls from the school - he's sick - stomach upset, etc.
Finally after a month of this - I was UPSET - REALLY upset as we had taken him to the doctor - nothing wrong - I said - we cannot keep doing this. What is going on. He said "I hate school" - we were in the car - I almost slammed on my brakes - what? I hate school. Why?
He had stopped a bully in Kindergarten - he kept pestering him - he was in TKD and handling it - we were teaching him to deal and not let some piss ant bully get the better of him - nope - that's not it. I'm letting people see him for the bully he is...okay - what's up. Ms. Cox (I'll not use her real name) says some of us kids in the class are stupid. I pulled over and said WHAT?
Let's roll play...
Son as Teacher "I can't believe you are that stupid"
Son as himself "I am trying hard"
Son as Teacher "No you are not. You're just like John - Stupid"
I lost it. I drove to the school and confronted the teacher WITH the principal. She, of course, denied it. Called my son a liar...I flipped a switch and told her that this is UNACCEPTABLE - well - the teacher is BLACK and it's a union....it took us 6 years to get her out of that school.
I talked with other parents...they were upset too - but felt like if they complained they would be called racists and worse - they were afraid of retribution on their younger kids. So they did NOT step up...I was NOT happy.
You need to get her in the car - for a longer trip - and start talking about TKD - what she likes...don't ask "what's wrong" - ask what's right and that will lead to the issue....that's why I say car ride...she can't run out...she can't say she didn't hear you...
Then talk with Sabumnim. He needs to know what is going on in his dojung.
Good luck!
