But even in animal life, and still more in our own, Affection extends far beyond the relation of mother and young. This warm comfortableness, this satisfaction in being together, takes in all sorts of objects.... Its objects have to be familiar. We can sometimes point to the very day and hour when we fell in love or began a new friendship. I doubt if we ever catch Affection beginning. To become aware of it is to become aware that it has already been going on for some time. The use of ‘old’ or vieux as a term of Affection is significant. The dog barks at strangers who have never done it any harm and wags its tail for old acquaintances even if they never did it a good turn. The child will love a crusty old gardener who has hardly ever taken any notice of it and shrink from the visitor who is making every attempt to win its regard. But it must be an old gardener, one who has ‘always’ been there — the short but seemingly immemorial ‘always’ of childhood.
