Hospitality means primarily the creation of free space where the stranger can enter and become a friend instead of an enemy. Hospitality is not to change people, but to offer them space where change can take place. It is not to bring men and women over to our side, but to offer freedom not disturbed by dividing lines.
[O]ver the years I travelled to another universe. However alert we are, however much we think we know what will happen, antiquity remains an unknown, unanticipated galaxy. It is alien, and old people are a separate form of life. They have green skin, with two heads that sprout antennae. They can be pleasant, they can be annoying--in the supermarket, these old ladies won't get out of my way--but most important they are permanently other. When we turn eighty, we understand that we are extraterrestrial. If we forget for a moment that we are old, we are reminded when we try to stand up, or when we encounter someone young, who appears to observe green skin, extra heads, and protuberances.
