I want to tell you a story that changed my life many years ago. We were living in College Station, Texas and my wife and I were on our way home from Houston, Texas one Saturday morning. We decided to stop at a local restaurant to get something to eat since we had enough time. When we finished, we got back into our car and before I started it, we noticed a homeless man standing in front of the building. His clothes were worn and it looked as though he didn’t have any money. It was cold and I was sure he wanted something warm to drink; however, it was not this that I remember, because that is not what "moved" me. A dog was also walking up to the front of the building. Being a dog owner, I knew that the dog was a mother, and that she had just had some pups (小狗). She was hungry and weak and I felt bad for her. I knew if she didn’t eat soon, she and her pups would not live. People walking by didn’t even notice her. She was not as pretty and clean as most dogs, but she still deserved (值得) better. We still did not do anything, but someone else did. The homeless man, who I thought could not afford anything to eat, went into the store and bought dog food with all the money he had.
