Alex decided to spend a quiet evening reading in the park. As he settled on a bench, he noticed a small dog trotting around, seemingly lost. He looked around, wondering if someone nearby was looking for the dog, but no one appeared. After a few moments, Alex checked the dog's collar and found a phone number. A quick call later, and the owner was overjoyed to hear about their missing pet. They thanked Alex warmly, and as he walked home, he felt a small sense of joy from having helped reunite them.
