Ivy and Ted have been playing a game they call Fetch It lately, where he pretends to be her dog. I encourage this game because she is kinder to him as his owner than as his sister.
Overheard from outside their bedroom door tonight:
Ted: And then I will be eight and I will be a girl.
Ivy: (long-suffering tone) No, Ted, I've told you, you will always be a man.
Ted: (long pause) And then I will be fourteen and I will be a girl.
Ivy: No, Teddy. (Long pause). Well, you can pretend to be a girl.
She's in his corner.
