Girl Genius: Briley, can I have some of that juice?
Me: Sorry, not right now. It's almost dinner time.
GG: Well. Mommy & Daddy let me have it even if it's dinner time.
Me: But I'm not Mommy or Daddy. Do you remember why I drink juice?
GG: Something with your blood sugar. Too much?
Me: You're right. It is because of my blood sugar, but it is because I don't have enough blood sugar. And you know how juice has sugar in it? Well, the juice can put it in my blood to make me better.
GG: Okay *goes back to playing*
