    It has been said of man, “Once an adult, twice a child.” Young children are by nature dependent, require protection and security. There comes a time when the child struggles to get out from under the parents’ protective covering and exercise self-determination; to progress from dependence to independence. The Senior Citizen, too, often rebels against having his decisions made by others; he struggles against being treated like a child or as a nonentity by his own children and others.
