We can discuss that this is the very big problem of a school. this type of behavior is not at all good for student this shows how indiscipline they are,those students who do this type of activity they not only loosing there respect in front of there friends but also in front of teachers. we go to school for study and we should make discipline in school. but some students don't care they have destructive mind and they always want to destroy things.school furniture is like our home furniture so we should take care of it not destroy it.but somehow students do this and this is not at all a good activity. if any student do this type of behavior we should firstly complain to the teachers then we have to stop him by telling this is not a good activity for you and also for your reputation.
