A stranger was seated next to a little girl on the airplane when thestranger turned to her and said,
"Let's talk. I've heard that flights go quicker if you strike up a conversation with your fellow passenger."
The little girl, who had just opened her book, closed it slowly and said to the stranger, "What would you like to talk about?"
"Oh, I don't know," said the stranger. "How about nuclear power?"
"OK" she said. "That could be an interesting topic. But let me ask you a question first. A horse, a cow, and a deer all eat grass, the same stuff. Yet a deer excretes little pellets, while a cow turns out a flat patty, and a horse produces clumps of dried grass. Why do you suppose that is?"
The stranger thinks about it and says, "Hmmm, I have no idea."
She said "Why do you feel qualified to discuss nuclear power when you don't know sh1t?"
