After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students．Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize hot to be polite and thank others．Once they’ve been told, they’re halfway there．

When we have to go up moving stairs, we will stand to the right． That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs． When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter．

This seems so simple, but it is surprising how many kids have never been told to do this． Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth．One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible．If not, they will be passing those germs （细菌） along to everything and everyone they touch．

If you come to a door and someone is following you, hold the door． If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through． If the door opens by pushing, hold the door after you pass through．
