First,it’s important for us to speak politely. We must respect the others. When I meet someone I know , I often greet him by saying hello to him happily. We are supposed to be kind to others, warm-hearted to everyone, and generous to our friends. Second, we can’t throw rubbish everywhere. We must throw them in the rubbish bins. Littering is not a good habit. Every time I go to the park, I always pick up the litter and put it into the bin. I think if we all do so, the world will be cleaner. Another important thing is that we must follow the rules. There is no doubt that waiting in line is the important rule. I never rush into the bus. Waiting may be a happy thing. I foten feel happy when I do something that is better for us. I think being a polite middle school student is proud.
