As I waited in a post office line, I watched the clerk. She looked to be so deep into the doldrums that she could barely hear her customers. It seemed that, when she finally took in a request, she'd move in slow motion, lethargically searching through stacks of paper with her eyes half closed and her mouth half open.
As the minutes ticked on, I became annoyed. Then I thought, "Oh, I'd hate to have her job." So I was feeling more empathetic when it was finally my turn. By then, nobody was behind me in line, so I engaged her in conversation.
