FIC: Substitute (1/?)

Title: Substitute (1/?)
Fandom: Doctor Who, Amy, River/Eleven, probably Rory in future sections
Length:  944 words in this section
Rating: PG, no warnings
Spoilers: "The Big Bang"
Summary:  AU from "The Big Bang:" Amy begins to realize there's something wrong with her life.
AN: --Written for the spoiler_song  ficathon.  Prompt by beerbad : River + Eleven + Amy, AU end of S5 - Amy wakes up and it turns out River and the Doctor are her parents... somehow  (I CANNOT SHAKE THIS PLOT BUNNY FOR THE LIFE OF ME).  OMG, beerbad, I can't either.  Awesome, awesome prompt.
--This should, by all rights, be total crackfic, and yet almost nothing you can write for this fandom really feels like crack to me. 
--Also: I am an American, and this proved to be a greater difficulty in writing for a domestic setting than it does for your average space adventure.  I did my best, but I would be most grateful to anyone who can correct any really egregious Americanisms.  Don't talk to me about spelling, however; life is too short.  ETA: thanks to stick_poker  for a britpick.
--I've got ideas about how to continue this.  Feedback very welcome.


( Amy (Amelia) Pond awoke, as she did most days, to the sound of birds singing outside and bickering downstairs . . . )
