"A charismatic figure, Jackson was combative, quick-tempered, and thin-skinned. To his friends he was generous, considerate, and above all loyal; to his enemies, mean-spirited and spiteful. "When Andrew Jackson hated," Robert V. Remini, a modern Jacksonian scholar, has written, "it often became grand passion. He could hate with a Biblical fury and would resort to petty and vindictive acts to nurture his hatred and keep it bright and strong and ferocious." He at time exploded with anger, but it is believed that he never really lost his temper. Rather, he launched into tirades quite purposefully either to intimidate his opposition or to end debate on a matter that was dragging on too long. Martin Van Buren, his closest adviser, marveled at Jackson's ability to turn his anger on and off at will. One minute he could be shrieking at the cabinet in the high register his voice invariably had whenever he was agitated; the next moment, alone with Van Buren after the others had left, he was relaxed and in good humor. At social occasions Jackson surprised many with his grace, poise, and charm. Around women he shed his backwoods manner and earthly language to engage comfortably in social discourse. He delighted in disappointing those who, he said, "were prepared to see me with a tomahawk in one hand and a scalping knife in the other.""
