The day that your bathtub drain gets blocked up beyond any hope of home remedy and there is no way you are getting a plumber will be the very day your kid comes home from playgroup with unidentified blue stuff that is neither paint nor play-doh but has the worst properties of both stuck to his face and hair, crammed under all his fingernails, and caked to his arms up to the shoulders.
What's a mother to do? Why, pull a chair to the kitchen sink, squirt in some dish soap, run the hot water and throw in some sandbox toys. And let the kid climb up and play with bubbles.
And take pictures, of course.
He's pretty clean now. The floor, on the other hand...
