In the wake out the latest pathetic disaster from the publishing world, allow me a moment to provide a little public service to all you wanna-be memoirists out there:
From the American Heritage Dictionary:
mem·oir (měm'wär', -wôr') n.
1. An account of the personal experiences of an author.
2. An autobiography. Often used in the plural.
3. A biography or biographical sketch.
In other words, if it didn't happen to you (for reals) it's fiction. Sell it as such.
