I wonder if this impulse to share, the urge to elbow your neighbor, who maybe was not even your neighbor until the bird flew between you up into the pipes and rafters you did not notice until you followed the bird there, is also among the qualities of delight? And further, I wonder if this impulse suggests—and this is just a hypothesis, though I suspect there is enough evidence to make it a theorem—that our delight grows as we share it.
