School these days

Well today my son Josh came home and asked me "Mom if a teacher told me not to tell you something, should I tell you?" I told him yes. He says that he and three other kids were called out of class and two teachers were accusing them of bulling a girl. He says that he didn't do anything to the girl, that the girl is calling them names and talking behind their backs. He said the only thing I did was that I saw she was listening to the Red Hot Chili Peppers and told her they were cool. He said I also told her to lay off and stop talking behind peoples backs. Is that bulling. The thing that upset me the most is the way the teacher handled the situation. She said "that _________ was getting teased for reading a book you should put down the stupid nintendo and read the F----- book." What in the world. I am blown away. I am ticked. She should have thought before she talked to my son like that.
