To forget is the secret of eternal youth. One grows old only through memory. There's much too little forgetting.”
Erich Maria Remarque, “Three Comrades”.
“Every man has reminiscences which he would not tell to everyone, but only to his friends. He has other matters in his mind which he would not reveal even to his friends, but only to himself, and that in secret. But there are other things which a man is afraid to tell even to himself, and every decent man has a number of such things stored away in his mind. The more decent he is, the greater the number of such things in his mind”. Fëdor Dostoevskij (Notes From Undeground)
