He had thought he was reading fan fiction, in a surprisingly well-appointed garage. But he was actually on an alien space ship. Oops.

I love it because it embodies the situation we are all in, and which art must remind us of. Hey - Wake up monkey man - you live in a very big thing, and there isn't a script. That's the real realism. SF is more realistic than conventional literature. Hello! Earth to Communicator! Houston, do you read?
You will note of course that the Chillis expressed it so much better than I can, in the track which I can't stop using for my headers.
