what if a teacher at school treats your child bad?

oh my God what? have you ever been treated badly before, by anyone at all, maybe that would make you change your mind with all due respect, i dont agree with you. children need love and good treatment inorder to survive school and acquire an education. can i tell you that i had a teacher who used to beat kids in class and for that reason i skipped that class, i was so scared, he beats student when they are late, if am late ,i just go back home and make up stories about being sick or something. i can tell you from experience that students who are treated badly in schools dont usually learn very well, are usually afraid, withdrawn etc. but you know what they say, there's always an exception to the rule. thank you so much for responding (take no offense ok)
