One day, a boy named Tim wanted to sell his toys. He put them in a box and went outside. He put a sign that said "Toys for Sale". Tim waited for a long time, but no one came to buy his toys.
A girl named Lily walked by and saw Tim's toys. "Wow, you have modern toys!" she said. Tim smiled and said, "Yes, I want to sell them. Do you want to buy one?" Lily looked at the toys and said, "I have zero money, but I can trade you one of my toys for one of yours."
Tim thought it was a good idea. So, they traded toys and both were happy. They played with their new toys all day. From that day on, Tim and Lily became good friends and always shared their toys with each other.
