In response to the following parable:
A boy steps onto a train. The train stops, and, through the doors, he sees a sign that says 'College.' The boy laughs, and the train continues moving. Again the train stops, and he sees 'Graduation.' He stays on the train. The train stops at 'Career,' and the man laughs. "No way. I'm a free spirit." The train stops at 'Family and Children,' and the man says, "No, not for me." At last, the train reaches a stop that is unmarked, and the old man stays in place, but the train does not move again, and he knows it's his time to get off.
