Properly handled, parent-child relationship will leave neither of both sides a sense of loss. It is periodical happiness for parents to have interaction with children when stepping into middle age. However, we should not attach much serious significance to it, nor should we consider it insignificant. Children should not bear the deeply ingrained love of parents in mind for lifelong, which would hinder them from growing up. Nor should parents always remember the sacrifice they have made to their children, which would make the elderly feel trapped in the self-pity of expecting rewards. And. in fact, children have already fully reciprocated with baby-talks, hugs, and remarks likes “Mummy, I love you so much!” or “Daddy, I gonna marry a good man like you!” Yes, all of these are their love in return.
