Often, meeting years later some friend of our youth whom we never particularly liked, we scarcely trouble to shake hands with him, and yet, did we but think of it, it is from a casual remark which he made to us, “You ought to come to Balbec” or something of the kind, that our whole life and our work have originated. But if it does not occur to us to thank him, this is no proof of ingratitude. For when he uttered those words he had no thought of the huge consequences which they would have for us.
