Overheard as Jerry talked with his playdate .
Jerry: "its just like when people ask me what its like not to have a Dad? How am I supposed to know? I've never had a Dad. So to me its just normal. But for someone else, it might not be. Its just like Physics. If you're riding on a car thats on top of a train, and the car is going 2 miles per hour and the train is going 100 miles per hour, if you are in the car, you think you are going 2 miles per hour, but if you are watching the train go by with the car, the car is going 102 miles per hour. Its all relative."
Physics explains the universe in more ways than I knew!
