'Being kissed by Wyoming Knott is more definite than being married to most women'
-The Moon is a Harsh Mistress, Heinlein.
I really like this quote because it leaves the exact mechanics of the kiss completely open to interpretation, but the reader knows EXACTLY the feeling he's describing. There's a reason that Heinlein is a master.
(I was re-reading The Moon is a Harsh Mistress because I like how it portrays the development of an AI)
Whom the gods notice they destroy.
-The Man in the High Castle by Philip K. Dick
EDIT: I love this let's do it every couple of weeks.
