I play a little game with my son where I ask him how much I love him. He replies in numbers. The joke is that he usually says, “zero” or “one.” Then I correct him with the craziest number I can make up, which is undoubtedly unscientific, followed by tickles and laughter. There is no number that can express quantitatively how much I love my children. Though we play silly games, my son knows that I love him. He believes it. He trusts me, he trusts in my unfailing love.
