Note 16 — Chapter Nine
Reading edition
... except for the unique form of restraint Dave could exercise over his temper, I sometimes think he might have been subject to Father’s kind of outbursts of passion. But David literally worked off his rage. I have seen him run out of a room and chop wood or lug something heavy or go curry a horse when threat of anger began to rise in him.
In later life, he had a habit of abruptly leaving the room during a disagreeable conference. Usually, it was for nothing more than to gain control of a rising anger by pacing an adjoining room or indulging in a momentary and completely irrelevant task of stacking books or rearranging a desk, a power of restraint that was to stand him in good stead.
