The Doodie

So I am in the stall, going pee.
It's "Take Your Kids To Work Day" remember?
And two of them walk in. Mumbled talk...one boy, one girl.
She has to pee.
I'm done and washing my hands now.
She's undoing her diaper, he's standing right next to her in the stall, taking bites of his bagel.
She keeps saying, "That's a doodie."
I left.
