A decade is usually enough to transform a beginner into an expert. But what is more striking than the knowledge acquired in a discipline or profession is the obvious change that study tends to bring about in one’s surroundings. So much changes! Ten years later, the beginner has become a different person; physically, he is someone else, and it is sometimes difficult to connect the new expert with the person he once was. Someone who did not know him will no longer find those traits that led to his current state. And someone who knew him before, even if they try, even if they force it, even if they refuse to accept the change, will likely fail to strike old chords, and will end up realizing that they—thank God!—will never vibrate again.
