## New Years Eve Party Game

Last year I went to a New Year’s party. There were 8 children there and they all happened to be wearing black sweaters. My uncle gathered them together, found some chalk, and wrote one number on the back of each child. The numbers were: 1, 2, 3, 4, 5, 7, 8, 9. My uncle then asked whether it was possible to arrange the children into two groups of four, such that the numbers on the backs of the children in each group came to the same total. After much messing around, we managed it. Can you?
