Summarize this article in one sentence.
Though you may have a lot to do, it’s nice to greet and welcome each arriving guest into your home yourself, rather than having another guest let them in.  This is their first impression of your new home, and greeting them yourself sets the best tone for the party. When each guest arrives, offer him a drink.  Give an overview of the options and offer to pour a drink for him.  If he declines initially, show him where the drinks are and encourage him to help himself whenever he is ready. You may want to wait until a small group has arrived so that you don’t have to give as many individual tours.  Guests love to see all of the rooms of your new home, including closets and pantries.  If you have any unfinished rooms, ask guests if they have any suggestions for how to use or organize the space.  This will take the focus off of the fact that you’re not unpacked yet and give guests an opportunity to feel helpful. Feel free to tell guests that they cannot go into certain rooms.  It is your home, after all, and you do not have to show everyone every room in the house. You may want to put all the food out at once, but you can also put food out in waves.  You could start with 2 or 3 food trays, then add to them or provide new things as the evening progresses.  Encourage your guests to eat and ask them about any dietary restrictions or allergies as you direct them towards the different food options.  Consider keeping the food and drink areas separate to avoid crowding. Providing two or more locations for food can also prevent crowding. Try not to spend too much time with any one party guest, but circulate around and speak with everyone.  Be sure all your guests know each other, and if you are introducing two people who have never met, try to point out something that you think they may have in common. Remember that people may have different styles and visions for homes, and that some of your guests may not have the privilege of owning a nice home.  Always be gracious and be genuinely grateful that your guests have come to see and celebrate your new home with you. If you plan to serve a sit-down meal, try to serve it at the appropriate time.  Most of your guests should have arrived, but no one should have been there long enough that they feel ready to leave. Towards the end of the night, consider serving your guests coffee and dessert (if you did not have dessert trays out already).  This will be a signal to your guests that the party is winding down, and providing coffee before guests drive home is a nice way to help keep them safe.  Be sure to thank guests for coming before they leave.
