Letter 2
Dear Mary，
Cook something that would let you spend time with your guests. If a guest offers to help you in the kitchen, accept the offer. It often makes people feel more comfortable when they can help.
Before serving dinner, while your guests make small talks in the living room, offer them drinks. Some guests may like wine, but make sure to provide soft drinks for people who don’t.
At the dinner table, let your guests serve themselves. Offer them a second serving after they finish, but don’t ask more than once. Most guests will take more if they want.
Perhaps the most important rule of all is to be natural. Treat your guests as you want them to treat you when you’re in their home—that is, act naturally toward them, and don’t try too hard to be polite. Have a good time in a pleasant atmosphere.
Yours,
Vida
