Etiquette says: A good host or hostess should provide a guest book by the front door.
Here’s my suggestion:
Indeed! Get a guest book! Beside it have a box of silly glasses, hats and signs. As each guest walks in the door insist that they choose one to put on. Guests could be anyone that steps inside the door, Fed Ex Delivery Person, your kid’s school friends, important politicians on the campaign trail … you get the idea. Take a picture for posterity. Place in guest book.
