Lizzy laughter!

So, just a moment ago, I was kind of half-way listening to Lizzy tell me something.  She asked if I'd like to try making rock candy again, and said "Did you know that rock candy used to be used as medicine?"  

   I said I didn't know that.  Then I jokingly asked her, "How do you know so much, smarty-pants?"

Without even missing a beat, she said, "I don't read.  I watch TV."
