"I'm Shrinking!"

While playing in the bathtub tonight, you said “Help, I’m Shrinking!” I replied, “you’re shrinking? What does that mean?” not expecting an actual definition. You looked at me and put your fingers together and said “I’m getting smaller, and smaller, and smaller.” I was amazed that you knew what the word meant and that you could give me a synonym for it! You are well beyond your years!
