I think I will quit!

I really don’t know if the management should get involve in every _ I mean every!_ detail of every class or what?
For the past 2 weeks I had difficulties with one of my students... he is a bit hyper & I really can't control him. He is 7 years old & I thought he would do better in a lower level with less discipline in the classroom, since he is always standing in the middle of the class & he never pays attention to what I'm saying. So I had a talk with management & her mother was there to make a decision about him attending my class. & the result is he is staying. Well, I really don’t want to get into the details but my boss spend the whole time of last session in my class repeating the lesson for him! & well, unfortunately, she had never taught English & she kept meddling with teaching telling my students what to do. Then she told me that I was "say to much 'be quite' or 'why are you talking" in the classroom!
I really don’t like it when people who don’t have the actual knowledge tell me what to do. I asked to divide my class into tow classes so I could have more time with my students. It was rejected. So I asked them to find a sub teacher for the class.
I think I should have never tried for the teaching job! But anyway I learned something & that's the best of the experience; so there is nothing to regret.
I never thought I would give up so easily. I used to fight for the things I would start. If I had any doubt, I would not start something but this once.... Well, I'm going to spend the rest of my days as a teacher with a new method. I hope it would work....
The only thing I wish is my students would remember me as a nice teacher. That's all for now.
I have class tomorrow... pray for my nerve.
