Mournful and mad

One has all the symptoms of clinical depression. “A reluctance to come out of his shell,” said one psychiatrist. Another noted: “Slow, laborious movements, indicative of lethargy, compounded by a wish to spend long periods asleep. Even when awake, has a mournful expression.”

Another, by contrast, appears to have a hyperactive attention deficit disorder. An inability to concentrate without twitching. Prone to frenzied running, coupled with aggressive behaviour, manifested by the stance of a boxer. Often described as mad at a certain time of the month.

Still, what do psychiatrists know? It seems normal behaviour for a tortoise and hare.
