Courtesy – Treat others with the respect that you expect to receive yourself. If you do treat other people with respect and courtesy and you will receive it in return. If you were rude to strangers what would they do to you? Be rude back? Yes, at the very least. If you are courteous to people what do you think they do in return? Isn’t life far simpler if we all get on and are not constantly at odds with one another. Courtesy and respect are the first steps towards this. Try it. Ask for something and watch the response. Try again and say ‘please’ and ‘thank you’ and see how people are far more helpful.
