I'm volunteering to throw a Christmas party for boys in a group home. There are two group homes we are working with, so 20 boys in all. We are going to throw a bowling party, and then go into a private room for an activity, food, and presents. Last year I did an ornament craft.. we talked about the birth of Jesus.. wrote down one thing we can each do to bring peace into the world.. put it inside the clear plastic ornament and decorated it. Most of the boys got into it. But now since we will have all 20 boys together at one time, and inside a bowling alley, I have no idea what to do. Any ideas?
