Yesterday, Nora saw me taking pills from a prescription bottle.

Nora: KK, are you sick?
Me: No, I'm not sick.
Nora: Then why you taking medicine?
Me: Because I'm crazy.

And then later...

Nora (really excited): Mommy, KK takes medicine because she's crazy!

I'm going to teach her to follow that up by shaking her head wildly back and forth like a nut.
