We were not perceptible

It was like crossing a border. I remember a dense crowd and a sort of humiliating difference. I looked not at the boys but at the girls, the women: they were absolutely different from us. They seemed to have breathed another air, to have eaten other food, to have dressed on some other planet, to have learned to walk on wisps of wind. I was astonished. All the more so that, while I would have paused to examine at leisure dresses, shoes, the style of glasses if they wore glasses, they passed by without seeming to see me. They didn't see any of the five of us. We were not perceptible. Or not interesting. And in fact if at times their gaze fell on us, they immediately turned in another direction, as if irritated. They looked only at each other.
