What is a home? It is a familiar base that protects you, provides for you, while making great demands on you as time goes on. The servant slowly becomes more of a master.

But too much reliance upon a past home prevents a new one from having a chance to form. We push our children out of their nest as part of our parental duties. Who, then, will push us out when we are the only one in the nest?
