Bring one balloon for each person in your group and a couple of permanent markers. Pass the balloons out and have them blow up their balloon.
Ask your group: "What in your life are you celebrating today?" Then have them write their answers on their balloon. Take time to share what each person wrote, and then, after each person has shared, have them throw their balloon in the circle on the floor. When everyone has shared, simply make a comment about how we have lots to celebrate in our lives and that we should share those things with one another. It will bring a sense of "party" to our everyday living.
