Children will love and respect their parents if they have been brought up in the same way. As parents age, it is the children's duty to help and care for their parents as they were cared for themselves when they were young.

Children should love their parents, but the only "duty" of a child is to obey his or her parents. Obedience will always make a parent happy and pleased with the child. Obedience will also cause the child to love the parents and to have a desire to care for them when they are older.

yes, Obedience counts a lot. :)
