Students were always prey to a kind of restlessness, I said, because as long as they are at school they live in a no-man’s land between the parents they have left behind and the world they cannot yet attain, and their instincts still draw them back to their parents rather than toward the world. There are often tragedies inside that no-man’s land, which happen when they realize that they can neither return to their parents nor step out into the world.
