Gestures matter. For example, Vito is always courteous and even kindly to Tom, and Tom never acts subserviently to him. But, Tom is still his subordinate. In the opening scene, as the camera starts to pan away from Bonasera's face, and Bonasera breaks down, Vito makes a snappy, ordering gesture to Tom to get Bonasera a drink. Later, at the Commission meeting, as Vito starts talking, he gestures to Tom to move his chair for him. Both beautiful touches.
