do so from habit and not because they know that soon they will become parents.
Only people know how babies are born and they are the only creatures that plan to live together and have children. Like the animals a man and a woman may feel like sending the sperm to join the egg but they do not do this unless they love each other. A human being does not choose as a mate the first person he or she meets after having grown up. Each man and each woman waits to marry the one whom he or she can love. Rather than marry some one without love some people never marry at all. When a man and a woman take each other as mates they love each other so much that they want to live together always and to help their children to become strong and happy and useful.
This is the most wonderful and the most beautiful part of the story of how we grow and are born and grow up. Each one of us starts living because of the love of his parents. You came into the world because your mother and your father loved each other so much that they started you growing to be a baby.
