In a village where there were not many trees lived a family that owned the local corner shop.
One day a huge van came to deliver the stock and with it came ten boxes full of chocolate but the family had never heard of chocolate before. So the mum of the family took one bar and tasted it.
“This is lovely, let’s sell them!” she exclaimed.
So they did, suddenly everybody had heard of the new thing so they bought loads each. Then the son in the family asked for two chocolate bars. The dad went to the chocolate box, “But ‘I'm afraid it’s the last one," he said.
