A conversation

 A stranger was seated next to a little girl on the airplane when the stranger 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.'
To which the little girl replies, 'Do you really feel qualified to discuss nuclear power when you don't know shit?'
