All of us are more interested in raising up the children in best of the schools and colleges "of course it is not a sin " but moral values have to be tought or communicated to children.Parents If they have communicated well about moral values will never have such problem. We should try and talk to our children every day and understand their problems and difficulties that they go through everyday.Every child in modern day is facing a problem which vary from one to an other,Some have problems in learning, some in acceptance , some in lisening , some in reading ,and some in handling emotion like ,anger ,fear , joy .We as parents should understand what they want and communicate it to them.
Techers on the other hand have to tech moral values and disiplines in the way kids will understand,And report to parents in case of any misbehaviour.
