It's a Big World After All

This evening, Jack and I were sitting on the front porch swing. Jack asked me, "What's on top of outer space?"

"Nothing." I told him, "Outer space goes on forever."

"But I mean, what's on top of it?"

"There's nothing on top of it, Jack. If we got in a rocket and flew into outer space and kept on going and never ever stopped, we would still never reach the end of outer space."

He thought about this for awhile, then replied, "I think I'll just stay here."

Sounds good to me.
