Finally! The first line!

I've been trying to start writing a short story, and I know the entire form of the story, and the characters, and their histories, and what happens.  But what I didn't know was the opening line!  Finally, today, it came to me.   I've got a couple hundred words started on the story now.  First lines are so important.  Without them, the entire rest of the story either shows up begrudgingly or not at all!
