There is a non-zero chance that my life since about, oh, 1989 or '90 has simply been a lengthy, detailed dream. '94 at the latest.
Things as simple as Amazon: there used to be a purveyor of Victoriana/Civil War-era stuff called "Amazon Vinegar & Pickling Works," and I ordered items from their mail-order catalog. What if they were online and sold everything, especially books?
The World Wide Web is just the old e-mail+Usenet News Internet revved up and in full color.
eBay and Etsy? Wouldn't it be great if there was a hamfest/junk store that was open 24/7/365?
The Freewrite/Alphasmart/The Writer devices are just my old manual typewriter, made convenient and paper-free.
Blogging and my pal Tamara Keel? I'm a very shy, introverted person and a bit agoraphobic. Wouldn't it be great if there were a way to meet people that wasn't in person and didn't involve leaving the house? And what if one of them became my best friend?
And on and on. Of course, now I'm starting to feel the touch of age, with arthritis and poor eyesight; the dream may be taking a dark turn. I still think there's a small but non-zero chance that I have been hallucinating for thirty years, and God only knows what kind of terrible real world is really out there.
