I once heard of a child who was crying, because he had shoved his hand into the opening of a very expensive Chinese vase and then couldn't pull it out again. Parents and neighbors tugged with all their might on the child's arm, with the poor creature howling out loud all the while. Finally there was nothing left to do but to break the beautiful, expensive vase. And then as the mournful heap of shards lay there, it became clear why the child had been so hopelessly stuck. His little fist grasped a penny, which he had spied in the bottom of the vase and which he, in his childish ignorance, would not let go.
