I went to a union thing he was at and I took along a copy of Going on a bear hunt. I told him about a child I was teaching who was autistic but knew this book by heart and we used it when he was stressed. I apologised for the cheek but he had already taken it from my hand and signed it and drew a picture.
I gave it to the boy in front of his mum. She cried, he couldn't stop beaming and it was a moment of my teaching life.
