I learned an important lesson this morning. If your toddler asks, "May I please draw wiff dis black pencil?" it is wise to put your glasses on and make sure it really is a black pencil (as opposed to, say, a Sharpie marker) that she's holding.
Otherwise, she'll go to church with black fingers and a few extra beauty marks.
And if she says, "Mommy, I drawing onna wall wiff my blue pencil," you might consider that she's being completely accurate.
