In which the tables are turned

(While driving...)

Me: "When you're bigger, I'll teach you to drive a car, OK?"

Elizabeth: "I already know how to drive a car."

Me: "Oh... OK."

Elizabeth: "But, when I'm bigger, I want a new bed."

Me: "Why's that?"

Elizabeth: "Because I'm too big for my bed."

Me: "Of course! Yes, you can have a new bed when you're bigger."

[pause]

"You know what I want when I'm bigger? A bigger house."

Elizabeth: "Why?"

Me: "Because we're too big for our house."

Elizabeth: "I don't want a new house."

Me: "But, it might be fun to have a bigger house...?"

Elizabeth: "Well... we'll see, OK?"
