Enjoying Dinner with Friends

　　Americans, like many people elsewhere in the world, like to invite friends to their homes for an evening of food, drink and conversation．Formal dinner, in fine homes and hotels in the United States are much the same as formal dinners anywhere in the world．But as most people in the United States have no servants, their dinner parties at home are decidedly informal．Guests may sit down at a table, or, as many new small homes have no separate dining room or very small dining space, guests can also serve themselves and eat in the living room, holding their plates on their knees．

　　A more enjoyable form of entertainment is the picnic．Americans are great picnickers, and almost every family has a picnic basket．Summer invitations are often for a picnic at a park or in the open countryside．Unless hamburgers or hot dogs are cooked over a fire, picnic food is usually cold sandwiches, salads, potato chips, pickles．Watermelon is a favorite dessert, followed very often by baseball for the young and active, and naps(打盹)for the weary(疲惫的；困乏的)．
