Good manners is becoming something of a rarity in our modern society. When I open the door to let a woman go first I usually get reactions ranging from surprise to amazement.

In his article "Manners," L. Ron Hubbard says: "Good manners sum up to a) granting importance to the other person and b) using the two-way communication cycle"
"A person's importance is made evident to him by showing him respect, or just by assuring him he is visible and acceptable. To see and acknowledge the existence of someone is a granting of their importance. ... People have value and are important. Big or small they are important."
