At that moment he knew what his mother was thinking, and that she loved him. But he knew, too, that to love someone means relatively little; or, rather, that love is never strong enough to find the words befitting it. Thus he and his mother would always love each other silently. And one day she--or he--would die, without ever, all their lives long, having gone farther than this by way of making their affection known.
