"We don't love people and animals because we will have them forever; we love them because loving them changes us, makes us better, healthier, kinder, realer. Loving makes us stronger in the right ways and weaker in the right ways. Even if animals and people leave, even if they die, they leave us better. So we keep loving, even though we might lose, because loving teaches us and changes us. And that's what we're here to do. God sends us here to learn how to be better lovers, and to learn how to be loved, so we'll be better prepared for heaven"
