Teacher bullying

Amber
I wanted some input on what you ladies might think about this: my son came home from school yesterday and said that his teacher told him he was "so annoying" in front of the whole class, he is in 7th grade and he likes to talk a lot and always has, I was upset because I don't think she should have called him out like that in front of the class...I left her a message today to please call me as I would like to speak to her asap...would you consider this as a form of bullying or am I just over reacting???
