That's not usually how I write, but with this particular fic I did get an idea pretty early on for a final (or almost final) line that I thought would be funny, and then... it didn't work. Haha. So I just deleted it and ended the fic 87 words earlier!

Good luck! Don't forget, they only have to be 300 words, so you can think small if that'll make it more manageable for you. :-)
