I dont disagree but I have seen that happening that in cases where parents are extremely strict and they don’t get involved with the kids. Like I know few families who are so strict that they don’t even allow girls to dress moderately (jeans and full sleaves sweeter) at school. What does the girl do? They change at locker room at school.
What I stated is the essential part of the training i.e do what you want kids to follow off course it does not stop here. Get involved with the kids and try to understand where they stand.
and after all the effort parents have to understand that kids can not be raised 100% like they were raised back home. There always is going to be give-n-take at the end.
