"Mommy, you're a genius girl! You makes butts better by using fruit."
His butt hurt earlier, and he wanted to have a bath before he ate his dessert (frozen mangoes). I told him he had to eat dessert first because he was going to get all sticky. and although he complained, he ultimately complied. And then his butt randomly felt better and he gave me the above complement.
4 year-olds are weird.
