Every child from a very young age should be taught to say yes, please and thank you. To adults when they ask them if they want something. they should be taught to say thank you and may I be excused when they are done eating.

 When an adult is talking to a child they should look at you and tell you the answer to the question that you asked them. A child should not treat another child in a bad way. A child should not treat an adult in a bad way.

 Remember that child wills do what they see their parents doing. So the parents should be nice to each other. The parents should talk nice to each other.

 That way the parents are teaching their children to have the good manners.
