A、Keeping the same seats with familiar faces will be fun for everyone. B、Careful attention to details is the whole of the recipe

Hosting a successful party can give you a glow that will linger for days. It is easy to be a successful host: a few simple precautions, a little imagination, and careful attention to details are the whole of the recipe. If you follow that recipe, the party will be fun for everyone.
    The first step for a successful evening is to get a well-chosen guest list. Keeping the same chairs with the same guests party after party, however engaging and stimulating they may be individually, is as unimaginative and boring as to serve the same main course at every meal. If you change your guest list and bring in unfamiliar faces, you will offer your guests the possibility of discovery.
    The second step is to introduce your guests around as soon as they arrive. You must have the basic guidelines fixed in your mind: the man is introduced to the woman if she is over eighteen; the younger person is introduced to the older if both are of the same sex; girls under eighteen are introduced to older people; either men or women are always introduced to a considerably older person, and often to a person of special distinction. Newcomers should be introduced all the way around. When you have to leave a new guest with a group he has just met, tell them enough about each other so that the conversation will start easily.
    The way you seat your guests could perfect or spoil your party. Work this out carefully well in advance. Prepare notes on each guest’s interests, personality, communicational abilities. As a host, your responsibilities are not unlike those of the chairman of a panel discussion. You must pace the talk, spark it; see that all sides have a chance to get into the act. This is host mastery.
