Regret often attaches itself to things we did. Saunders points toward something quieter: the moment we could have been kinder and stayed at a safe distance instead. His phrase is powerful because a failure of kindness is not necessarily cruelty. It can simply be the decision not to enter another person’s experience when we had the chance. We cannot revisit every missed moment, but noticing this kind of regret can make us more available to the person in front of us now. Where might kindness ask you to be a little less reserved?
