Affection goes beyond the mother-child relationship. Almost anyone can be an object of Affection; it is not a very discriminating form of love, and the people it unites may not seem to be well suited to each other. It overcomes all sorts of barriers—between age, sex, class, and even species. Literary examples include Dox Quixote and Sancho Panza, or even Mole, Rat, Badger, and Toad in
The Wind in the Willows.
