I'm scrubbing the bathtub this morning when my precious child comes in the bathroom to investigate what I'm doing. After I point out the obvious, we have the following conversation:
him: but, mommy, why are you using a toothbrush?
me: (while demonstrating) because it helps me get into the corners
him: but, mommy, on t.v. they said that the sonic scrub brush would work much better!
(uh...I think my kid watches too much t.v.)
