Thanks alot everybody for your valuable commends. I personally dont support this attitude anyways. Sending a 6 year old child out of the class is not secure also.I strongly disagree with Tingerbell's comment. School is not a military camp. 6 year old child should learn disciple from the teacher with love...not with such a shameful punishments which will hurt their little mind.Not only this, this particular teacher is showing negligence to the child and didnt allow to participate in a competition which he was well prepared and eaget to perfom. This kind of attitude is really shameful for a teacher.
