One day, a girl named Lily went to the park to collect pretty rocks. She saw a boy named Tim with a big bag. Tim had a useful bag to hold his rocks. Lily wanted to be friends with Tim.
"Hi, I am Lily. Can I help you find rocks?" she asked. Tim said, "Yes! Let's find rocks with spots on them." They looked and looked, but they could not find any spot rocks.
Lily and Tim started to feel sad. Then, they saw a dog with a spot on its fur. The dog was digging in the ground. They went to the dog and found many spot rocks. Lily and Tim were happy and became good friends.
