The big hug

"On opposite sides of a quiet street lived two friends. From morning to evening, they played. You two are stuck together like glue!...So it was a shock when, one day, they had to stop and go inside...Where can you put friendship when friends are apart? Slowly, they learned. They found that, across the street and through windows, they could give each other a hug. They discovered that a smile is a hug. A wave is a hug"--.
