From Seth Stevenson, an appreciation of leaving social occasions without saying goodbye.
These sorts of goodbyes inevitably devolve into awkward small talk that lasts too long and then peters out. We vow vaguely to meet again, then linger for a moment, thinking of something else we might say before the whole exchange fizzles and we shuffle apart. Repeat this several times, at a social outing delightfully filled with your acquaintances, and it starts to sap a not inconsiderable portion of that delight.
