“When two members of a family or two intimate friends are separated, and one goes abroad and one remains at home, the return of the relative or friend who has been travelling always seems to place the relative or friend who has been staying at home at a painful disadvantage when the two first meet. The sudden encounter of the new thoughts and new habits eagerly gained in the one case, with the old thoughts and old habits passively preserved in the other, seems at first to part the sympathies of the most loving relatives and the fondest friends, and to set a sudden strangeness, unexpected by both and uncontrollable by both, between them on either side.”
