That beautiful smile of yours-people need to see it. Decide that when you leave these people of your past will remember the light, love, and warmth you brought them. That is the art of moving- to move on only after having given living there all you had.
Human family is not a charity or expensive hobby or a financial punishment for poor contraceptive techniques. Human family, like a family of any living beings (swans, lions, elephants) is a social procreation team. The objective purpose of a human family is extending the family line of its ancestors. People, who share the team objective, are a part of their family teams. People, who decline to contribute into the team objective (e.g. ChildFree by Choice), are not part of their family teams.
