There are many things in this world that move us. These things make us feel the warmth of life and the beauty of humanity. One of the things that touched my heart was something that I had experienced before. When I was in college, I volunteered to clean up the local community. That day, I came to a disabled family. There were only two people in this family, one was the father and the other was the mother. They were both seriously ill and could not live independently. I started to clean the room when I found my mother cooking in the kitchen. Her face was full of sweat and exhaustion, but she kept smiling and said to me,"Thank you, son. I'm glad you could help." I felt grateful because I knew that even though my mother could no longer live independently, she still needed someone to care for her. I feel very small, but I also feel very great because I can feel the kindness and warmth of human nature. From then on, every time I met someone who needed help, I would do my best to help them. I realized that everyone has their own difficulties, but we can still look at things from the perspective of others and try to understand their situation. This incident made me deeply realize the beauty of human nature and made me cherish the people around me more.
