2. In my life, I pay great attention to politeness, and there are many interesting things in it! One day on the bus, a white-haired grandfather came by. Seeing that no one gave up my seat in the car, I got up and gave my seat to grandpa. Another time it snowed heavily, and the snow on the road was thick. Not only is there a traffic jam, but even pedestrians can't walk. Without saying anything, I went out to help with the snow removal. Last time I saw an uncle littering, I went up and told him not to litter. My uncle finally praised me as a good boy ... that's what I said about etiquette, and I will always stick to it!
3. Also, say hello to your family every morning and evening. Say hello when you meet someone; Pick up the rubbish when you see it on the ground. These are all things we should do.
4. Look! Civilized etiquette is in these trivial things, which can be done without so much attention. I hope everyone can be a good teenager who understands civilization and etiquette.
