Being introverted to the point of misanthropy, I don't mind the alone time (which will encompass Simchat Torah as well.) However, being alone and unplugged? Good recipe for insanity.
Although it's two days, not four years, I keep thinking about the movie Cast Away. Loneliness can do strange things to people.
While I'm not at the level of befriending a volleyball, I can understand the impulse. Like the desert island, Shabbos is silent. No music. No needlework. No transportation. Sure, one can walk--where? I may try the beach. But what can one do in the winter? How much can one read? Or sleep? We'll see how it goes.
