Parents should remember that children are human beings not robots or goods. And the biggest investment a parent at his son is love and compassion. And love is not supposed to be counted with who owed whom and how hitung-hitungannya. Because love is abstract and not exact can calculated. Any parents had many flaws, errors and imperfections in raising his children, but a genuine love they will take her children always go back to them. Because giving love will get love back.
