How To Be Gracious - Esquire:
"You simply must attend. Stand when someone enters the room, especially if you are lowly and he is the boss, and even if the reverse is true. Look them in the eye. Ask yourself: Does anybody need an introduction? If so, before you say one word about business, introduce them to others with pleasure in your voice. If you can't muster enthusiasm for the people you happen upon in life, then you cannot be gracious. Remember, true graciousness demands that you have time for others."
