all i can say is that you better do something. such incidents could shape your son/daughter future.

i have already been through the system and after having studied in the Europe, i know how such things can effect negatively. no child deserves to be verbally abused by a teacher. yes, its called abuse if this had happened any where else in the western world.

sadly in some cultures, we have placed teachers on high pedestal from where they feel that they can do anything. if a child misbehaves in class then there are more effective ways to deal with them. so just goto the principal and have a strong chat with him/her.
