American poet and philosopher Ralph Waldo Emerson says, "Manners are the happy ways of doing things; each one a stroke of genius or of love, now repeated and hardened in usage. They form at last a rich varnish, with which the routine of life is washed and its details adorned."
Courteous people are happy people. Rude people are always unhappy, angry and miserable; and walk around with a chip on their shoulders. "The merciful man does good for his own soul, but he who is cruel troubles his own flesh." (Proverbs 11:17). How do you give and get respect?
