I was in McDonalds eating the other day when a child about 4yo came up to me and asked where poo came from. I looked around and saw a lady smile at me and nodded. So I told this child in detail the process of how poo is made. With his eyes wide open after I finished explaining where poo comes from, the little boy stood there and finally said and what about Tigger? I got up and left quickly after that.
