One of my favorite opening paragraphs:
Cities at night, I feel, contain men who cry in their sleep and then say Nothing. It's nothing. Just sad dreams. Or something like that...Swing low in your weep ship, with your tear scans and your sob probes, and you would mark them. Women—and they can be wives, lovers, gaunt muses, fat nurses, obsessions, devourers, exes, nemeses—will wake and turn to these men and ask, with female need-to-know, "What is it?" And the men say, "Nothing. No it isn't anything really. Just sad dreams."
First paragraph of The Information, by Martin Amis.
