I'm not sure quite how to explain this. Let me start at the beginning.
The children had read the story of the birth of Jesus and were now in the process of rewriting it as a story of their own. Most had only just begun relating the events leading up to the birth when Sam put his hand up and asked a question.
"What does accomplice mean?"
"Um... partner in crime would be the nearest," I replied.
"That won't do, then," he said, chuckling.
I looked down at his book. He had written: A long time ago, in Bethlehem, Joseph and his accomplice...
We chuckled over that one for some time.
