FREE PARTY GAME - POST: At big parties and dance music discos, in large halls it's very interesting to have "a postman". The guests ask him/her: "Give a note (a letter) to the girl in white dress". This girl writes her name on the sheet of paper and gives it to "the postman". All the guests communicate with the help of "the postman" until all of them learn each other's names. This can be fun when the dance music is too loud to talk.
