Pieces of pottery

Last week my two youngest daughters went on a school trip to a church where they learnt about the parables of Jesus - I think. It was a little difficult to work out exactly what they had done as the excitedly tried to tell me on the way home.

The plant pot in a plastic bag that had been thrust into my hand in the playground apparently contained a mustard seed. And there had been other stories too - there was one about a wedding, another one about a pearl, another one about hidden treasure.

They both brought home a small bag with a few items in that they had collected to remind them of the different stories. And they both had a piece of broken pottery. I never did learn what the piece of pottery was for, because it was at this point in the trip home that they descended into a full scale argument over whose piece of pottery was the biggest.
