So should it be with persons; if you kiss your child, or brother, or friend… you must remind yourself that you love a mortal, and that nothing that you love is your very own; it is given you for the moment, not for ever nor inseparably, but like a fig or a bunch of grapes at the appointed season of the year, and if you long for it in winter you are a fool. So too if you long for your son or your friend, when it is not given you to have him, know that you are longing for a fig in winter time.
