“Simply, eye management in our society boils down to two facts. One, we do not stare at another human being. Two, staring is reserved for a non-person. We stare at art, at sculpture, at scenery. We go to the zoo and stare at the animals, the lions, the monkeys, the gorillas. We stare at them for as long as we please, as intimately as we please, but we do not stare at humans if we want to accord them human treatment. . . .
With unfamiliar human beings, when we acknowledge their humanness, we must avoid staring at them, and yet we must also avoid ignoring them. To make them into people rather than objects, we use a deliberate and polite inattention. We look at them long enough to make it quite clear that we see them, and then we immediately look away. We are saying, in body language, ‘I know you are there,’ and a moment later we add, ‘But I would not dream of intruding on your privacy.’. . .
If we wish to put a person down we may do so by staring longer than is acceptably polite. Instead of dropping our gazes when we lock glances, we continue to stare. The person who disapproves of interracial marriage or dating will stare rudely at the interracial couple. If he dislikes long hair, short dresses or beards he may show it with a longer-than-acceptable stare.”
