Holiday season, you said. Well, we were on our way to Blackpool with our buckets and spades, young daughter singing in the back, me navigating. She thought I was correcting her words, so now its -
"Baa baa black sheep, have you any wool left?"

I used to supervise a playgroup, and took them on a country walk. "Oh look, there's a hare". James looked most apprehensive, I don't know what he thought a hare was, or how big.
And "look what I've found"... holding a newt on my hand. "Is it a crocodile?"

Being 4 must be a most confusing time.
