discusses the new genre of essays about the act (one I have often considered myself), and the etiquette of letting one's friends know via a status update:
Another thing I did not write about quitting Facebook was that one of the great social pleasures in my life has been to leave gatherings or parties unannounced. You know, when the party is socked in solid from the front door to the kitchen, and the conversation is drying up like old squeezed limes, it’s easiest to keep heading out the back. How cool the night. How open and unquestioning the darkness. “French leave,” we English speakers say. (“English leave,” the French say.) Often I went to parties to be able to vanish from them.
But the disappearing act rarely happens any more; I could never get away with it. Such pleasures one has to give up because they’re so unsuited to middle-aged life. You get trained, after a while, to going to every person in the room. Hey, great to see you again. See you later. Send me a note about that thing. Yes, let’s do that. Goodbye, bye. The book idea was, in a way, testing out the durability of that social grace. But I didn’t write about either topic.
