““Betty hugs me, and says, ‘Oh, Mummy, have you found a house? Is there a swing in the garden? You do look old this morning!’ Reply that I feel at least a hundred years old, and that I have found a house, but there is no swing in the garden. Betty’s face falls, so I rashly promise to see what can be done about a swing. She is overjoyed, and tells me that I do not look nearly so old as a hundred; only about sixty or so.””
