This could cause damage to the books. this will be followed by our younger. this would be a disrespect that we give to the studies. the students must realise the need of the poor who are longing to study. it would be good if the teachers advice this to the students. even if they don't want the books the teachers or the other students can get it and give to those who want. parents must also be strict with the children abt this issue. brothers and friends only can help them.
