Loss is a constant of living. As long as you live, as long as you continue to make connections and entrust others with your feelings, you will always be saying goodbye, always be letting go. And this can be a crushing reality – people can spend their whole lives seeking connections long past rekindling, and the grieving process is different for all of us. This letting go is perhaps not the cheeriest subject for a cartoon, but it is a powerful and deeply human one, and the ways we overcome the continuous goodbye of living can be inspiring in their own right.
