This works very much like "Secret Santa". We all draw a name from a hat and that person is our Advent Buddy. The mission is to serve our Advent Buddy secretly all throughout Advent. We might say extra prayers, make little gifts for them, make little sacrifices for them, or do their chores when they least expect it. I try to remind the children each day to do something for their Advent Buddy, some need more reminding than others, and of course the little ones need a little help coming up with ways to serve. Eventually they all get into the swing of it. It's truly wonderful to see the children looking for ways to serve one another.
