Many years ago, my church youth group went to the county fair. I bought some tickets for myself to ride rides, etc., and after a while I got bored with it and my friends and I just started wandering around. One of the little boys in our group (he was about 10) ran up to talk to his sister, whom I was friends with. I had probably 10 tickets left, I wasn't going to use them, so I said, "Hey, do you want these?"
"Sure!" he said, and ran off.
A little while later, I was standing in line for a drink, and he ran up to me again. "Do you have any more of those tickets?"
"No," I said.
"Can I have some money to buy some?"
"No."
