In a few weeks time, I’m hosting a supper party at home for about 30 people to celebrate a big birthday. It’s going to be informal, a mix of us cooking and buying salads from a local cafe for a stand-up buffet. But not everyone will know each other, and I wonder whether anyone had any good ideas for games/ice-breakers they have used to persuade people gently to try and talk to ‘strangers’ to make the party go with a bit more of a swing?
