Week Twenty: The elevator did not have a button for floor 5

Okay, so Freshman Me did not know how "elevator" is spelled.

If you can find it in your dark, withered heart to forgive the error, this week's prompt (the twentieth! that's a milestone, right?) is interesting in that it was intended to be the first line of a story. 

So! This could be your first line, or, like the others, you could use it as more of a thematic starting point.

The world is your oyster! (I hope you like oysters.)

500 words, Sunday, midnight, hoo-rah!
