If you want your guests to relax and get to know people, a good idea is as they arrive give the men a piece of paper with a gents name on, and the ladies the same with obviously a ladies name on. These must be the names of famous married couples iexample: Richard Madeley and Judy Finnegan Your guests then spend the evening asking questions without mentioning any names to find there partner. I went to one long ago and I was "Mary Wilson" and the question I was able to ask to the gents was, Are you in politics?, do you wear a mac? etc ect. until you discover who your "husband" is. If you need anymore explanation, please post again. Good Luck.
