Many years ago I was asked to visit a patient in a psychiatric hospital. When I arrived, the patient was with a nurse so I had to wait. I was shown into a large room. At first, I thought I was alone until I sat down. At the other end of the room sitting at a small table was a young woman. On the table was a jigsaw puzzle which she was trying to put together. She held up two small pieces of the puzzle that did not match. She tried to force them together, then she would drop one and pick up another, banging them on the table trying to make them fit. Then some fell on the floor, and she became more agitated. She looked down and said softly to herself, “The pieces don’t fit, the pieces don’t fit.”
