—How does a teapot birth a cup?
—The teapot and the cup were humans who were turned into a teapot and cup by a witch.
—How considerate of the witch to turn them into congruous items.
—The teapot sounds rather old to be the cup's mother. What's the story? Is he adopted? Was he conceived with a donated egg?
—What if he remained a cup? Would he become a teapot as he aged, like a caterpillar becomes a butterfly? Or would he be tragically trapped inside the body of a cup for the rest of his life? Does anthropomorphic porcelain even age? If not, would you rather be a mortal human or an immortal teapot?
