On Sunday, "Dear Abby" had three letters all revolving around politeness, giving us three good but often abused rules:
1. When bringing young children to another person’s home, watch them and make sure that they don’t damage anything.
2. People need compliments not criticism; it’s impolite to criticize for no constructive purpose.
3. When answering the door, for example, in receiving a package, hold your dog back—not everyone loves your dog, nor will your dog love everyone.
