The other day I walked into Margot's room and noticed a Polly Pocket mermaid tail lying on the floor.
Me: "Margot, whose is this? Jane has been looking for a Polly Pocket mermaid tail."
Margot: "Oh, that's mine. Jane has been talking about it because she has an Ariel Polly Pocket, but she lost the tail - so she can't use it as a mermaid. You know how she's obsessed with mermaids."
Me: [nodding]
Margot: "Actually . . . I'm not really using it so much. And Jane does love mermaids, and she does really, really want a tail for her Ariel Polly Pocket . . ."
Me: [waiting]
Margot: "So . . . too bad for her. It's mine."
