"Dear Darling Abby,
As delicious and refreshing as it may appear, that bowl full of water, which has the misfortune of being set at an all-too-tempting height within your reach, is in fact a TOILET and none of the following:
a drinking fountain
a hand washing basin
Please refrain from putting your darling hands (or anything else!) in this vile bowl meant for so much unspeakable human excretions. It is no place for a sweetpea like you to be playing. If you want to play in the loo, try the bathtub. It's the big empty vessel 3 inches away from that dispicable toilet you love to splash around in so much.
The Management, a.k.a. Mommy"
