“Usefulness is a useless concept when it comes to humans. I don't think we were ever meant to think about others in terms of their use to us. We keep pets for the pleasure of looking after them; we voluntarily feed extra mouths and scoop up excrement in little plastic bags, declaring it relaxing. We channel our adoration towards the most helpless citizens of all—babies and children—for reasons that have nothing to do with their future utility. We flourish in caring, on doling out love. The most helpless members of our families and communities are what stick us together. It's how we thrive. Our winters are social glue.”
