One day when my then 4-year-old grandson, Dmitri, was building a bridge with his wooden blocks, our playful puppy kept destroying it. Finally, frustrated Dmitri placed a triangular block at the top of the bridge as a sign announcing "No dogs allowed." I explained the puppy couldn't read his sign. So Dmitri turned to his mom and asked, "Will you read the sign to the dog next time he runs by?"
