Yesterday, while I was walking in the park, I saw a man sitting under a tree. He was reading a book, and there were some children playing nearby. One of them said, "Look, there is a dog!" The dog was running towards the man, and it jumped on him. The man smiled and told the children that the dog was his. The children were very happy and asked if they could pet the dog. The man said, "Sure, but be gentle with him." They were excited and started petting the dog while I was watching them from a distance.
