Healthy Advice

My mom and I were reading an encyclopedia about the human body. I was very interested in the pictures of two sets of lungs. One showed the lungs of a healthy person, and the other showed the damaged lungs of a person who smoked. Two days later some men came to our home to replace some carpets. I noticed one of the men smoking outside our home. Several times I heard him cough as he worked. I wanted to show him the picture of the lungs. When he was alone, my mom and I talked to him. I showed him the picture of the damaged lungs, and my mom told him that I was sad that he was smoking. The man smiled at me and said thank you. I felt good inside, and I hope he stops smoking so his lungs can be healthy.
