Do not interrupt grown-ups who are speaking with each other unless there is an emergency. They will notice you and respond when they are finished talking.
If you need to get somebody's attention right away, the phrase "excuse me" is the most polite way for you to enter the conversation.
When you have any doubt about doing something, ask permission first. It can save you from many hours of grief later.
The world is not interested in what you dislike. Keep negative opinions to yourself, or between you and your friends, and out of earshot of adults.
Do not comment on other people's physical characteristics unless, of course, it's to compliment them, which is always welcome.
When you have spent time at your friend's house, remember to thank his or her parents for having you over and for the good time you had.
When you make a phone call, introduce yourself first and then ask if you can speak with the person you are calling.
Be appreciative and say "Thank you" for any gift you receive. In the age of e-mail, a handwritten thank-you note can have a powerful effect.
Never use foul language in front of adults. Grown-ups already know all those words, and they find them boring and unpleasant.
Do not make fun of anyone for any reason. Teasing shows others you are weak, and ganging up on someone else is cruel. Be compassionate.
Even if a play or an assembly is boring, sit through it quietly and pretend that you are interested. The performers and presenters are doing their best.
If you come across a parent, a teacher, or a neighbor working on something, ask if you can help. If they say "Yes," do so -- you may learn something new.
When someone helps you, say "Thank you." That person will likely help you again. This is especially true with teachers!
Use eating utensils properly. If you are unsure how to do so, ask you parents to teach you or watch what adults do.
