Aliens.
You hear the term and you instantly get an image of something otherworldly. Be it little green or gray men with giant eyes or terrifying insect-like beasts with acid for blood, the "alien" in most of the stories we know is exactly that: a creature we cannot define because we are unfamiliar with what - or who - it is.
This edition of "Stories I Like, Love, and Hate" features the little green men from Mars and what I am always sad to see missing from a good alien story.
