Every man has some reminiscences
which he would not tell to everyone
but only to his friends.
He has others which he would not reveal
even to his friends, but only to himself,
and that in secret.
there are still others which a man is even afraid to tell
and every decent man has a considerable number
of such things stored away.
That is, one can even say
that the more decent he is,
the greater the number of such things in his mind
