A boy comes running towards me with something in his hand. Enthusiastically he asks: Teacher, what is this?!
I see a pair of chestnut shells in his hand, but before answering the boys' question I ask him: Wow those look cool! What do you think they are?
He looks at me, then looks at his treasure in his hand and says: They could be Hedgehog eggs!
I laughed out loud and was very happy I didn't tell him straight away what he had found.
