There is a lesson that I learned at twelve - the world does not end at the edge of a quad. There are people outside. The world does not end on the Fourth Level. There are people elsewhere. It took me two years to learn to apply the lesson - that neither does the world end with the Ship. If you want to accept life, you have to accept the whole bloody universe. The universe is filled with people, and there is not a single solitary spear carrier among them.
