A day with no edges.
Any day that has an airport, from which you text-message a person you once loved, and they write back, after 40 minutes: "Wow. Safe travels." And, feeling stupid, you stare out at the Manhattan skyline, observing how the Empire State Building is both absorbed into the silver gelatin sky and periodically released by it, when the gold light floods the sky just after dawn. Clouds. Newark. The feeling that you are about to get on a plane and travel in the opposite direction to what the heart wants. That kind of bittersweet melancholy and imperfect nutrition -- you've just ordered a fruit salad that seems to be fermenting in it's plastic tub -- constitutes the soft day with no misgivings, but a profound inability to think things through.
