Two good ‘uns; expecially Level by Keith Scribner which has much to teach about metaphor:
The Cats in the Prison Recreation Hall/Lydia Davis: Presents the major conflict in the opening line: "the problem was the cats…" to focus the reader then on the situation or event rather than bringing him in via setup of character or environment. Action includes side complications (skin conditions) and the resolution of the warden shooting the cats. End is a bit fuzzy and makes me believe that the whole story is a metaphor.
Level/Keith Scribner: This story is precisely metaphorical in its obvious use of the physical level against the relationship and balance of control (complete with conflict–buying things) within it. Excellently done. Even the ending balances the green bubble between the two (green-symbolic of money).
