The Rat pushed the paper away from him wearily, but the discreet Mole took occasion to leave the room, and when he peeped in again some time later, the Rat was absorbed and deaf to the world; alternately scribbling and sucking the top of his pencil. It is true that he sucked a good deal more than he scribbled; but it was joy to the Mole to know that the cure had at least begun.

We all need a friend like Mole.
