My wife and I are volunteer teachers in a class at church called the Nursery. The Nursery is a part of the larger Primary organization. Children start going to Nursery when they turn 18 months and they graduate into the Junior Primary when they turn 3 years old. Many of the new children go through a period of adjustment when they start out, which means a lot of crying and missing their parents.
So it occurred to me that we are Primary workers in the "Cry-mary" class!
