At a picnic yesterday, my husband (recovering from knee replacement) set one crutch down and, using the other crutch, walked to a picnic table nearby. One of the small boys grabbed the crutch on the ground and was told by an adult to "Leave that alone! It belongs to Uncle Bob."
"Well, why can't I play with it?" the boy protested. "Look! He has another one just like it! Doesn't he know about sharing?"
When a full explanation was given to the boy as to how the crutches are used and why Uncle Bob needed both, the boy's face fell.
"Oh," he said. "I thought it was a pogo stick."
