Sharing Christmas

It's the last day of school before Christmas break. The children gather around Mrs. C as she opens her gifts from the class. One by one the children share their gifts and their appreciation for their teacher. Yet one boy holds back, uncertain of his gift. Will he give his gift to Mrs. C? What gifts does she receive? The bell rings. Will he give his gift to Mrs. C.? What lesson does she have to share with him before he leaves?
