I'm on the flight home now.
It's a curious idea, really. Home.
As children we might make a game of it. You know, like when you play tag with your friends and you create a safe place where you can't be tagged. Even when we play games it's important to have a place to be safe...a "home."
When we played this game as children, however, we had another rule. You could not stay at home forever. You had to venture out. Sometimes the rule would be that you could stay home for 30 seconds and no more.
It's safe. You can't be tagged there.
But you can't stay forever, either.
