Affection would not be affection, if it was loudly and frequently expressed . . . It lives with humble, un-dress, private things; soft slippers, old clothes, old jokes, the thump of a sleepy dog’s tail on the kitchen floor.
C. S. Lewis, The Four Loves,
And I would add: laughter with old friends, a favourite movie or well read book on a rainy afternoon, home made soup and a gentle, knowing nod.
