I want to make some suggestions on your health. Father, I would be very grateful if you could give up smoking. You know, mom and I can't stand the smell of cigarettes. It's really bad if you continue to smoke every day. It will make your lungs black and make our family unhealthy. Mom, I think we need to do more exercise at home. Can we run on the playground every morning? I believe that if we exercise every day, we will be healthier and happier.
