“One of the hardest things to look at in this life is the lives we didn’t lead, the path not taken, potential left unfulfilled. In stories, those who look back — Lot’s wife, Orpheus and Eurydice — are lost. Looking to the side instead, to gauge how our companions are faring, is a way of glancing at a safer reflection of what we cannot directly bear, like Perseus seeing the Gorgon safely mirrored in his shield.”
(From a NY Times opinion piece. I had dinner with an old friend last night and we were going through the list of mutual acquaintances.)
