That's the secret of entertaining. You make your guests feel welcome and at home. If you do that honestly, the rest takes care of itself.
People are far more sincere and good-humored at speeding their parting guests than on meeting them.
As difficult as it is to have company within one's house, the absence of company is more so. The quiet echoing of solitary footsteps within the halls is suddenly amplified without the voices of excited guests. The clinking of plates and silver has narrowed to individual forks and spoons instead of the enchanting din of dining. The natural creaks and squeaks of the home are louder and more surprising.
