So I was taking a walk with my girls and I noticed a biplane flying overhead. I pointed it out to my 4 year daughter, Morgan. She looks up and exclaims, "Oh, a biplane!"
I was impressed she recognized it as a biplane. So we walk a little further. Then, out of curiosity I asked her, "so why do you think they call it a biplane?"
Without missing a beat she explains with certainty, "because they fly by!"
