Once upon a time, I was working at my desk, when I noticed that my youngest daughter was peeking over my shoulder. To amuse her, I made that two-handed rabbit hand shadow that everyone has done. She just rolled her eyes and giggled.
After a while, she asked "Daddy, do rabbits every make their own shadows?". I thought about it for a second, then replied "Yes sweetheart, I am sure they do. But, only when no one is looking!"
