Rockpooling today with 4yo DD. After a bit, she got bored so started a game where she pointed at a pool, and I had to see if "anyone was living there".
She pointed to a small pool near where she was sitting. Obediently, I made a show of searching through it. "Nothing in here!"
"No," she replied thoughtfully, "there aren't any snails in that one. Because it's made of my wee."
Anyone else care to share?
