Let me think about it...

Recently Lucy and I had a day in which we "grazed' all day, not eating a proper lunch but still eating quite a bit! Around 2pm, Lucy came up and asked, "Peanut butter sandwich, mom?" I answered, "Let me think about it." Lucy said, "Yes. OK. Think about it. Think. Think. Think." As she said this, Louise briefly crossed her arms, then closed her eyes while she tapped her forehead with her index finger. As she opened her eyes she exclaimed, "Yes! OK! Peanut butter sandwich!"
