Politeness, respect and consideration

should be precticed towards anyone in our lives, including our parents. But I am sick of such endless extaltation of parents '大爱'and expectation to return the favor. It is human nature that the old should nurture the young and let them fly away when they grow up. Such '大爱'can be seen everywhere in the animals world. The difference is that animals have the 'wisdom' to let go their young when they are old enough to survive on their own.
