Written for the EqD WTG #007. As always, comments are encouraged, and I once more make the request that everybody who chooses to like or dislike this story first leaves a brief comment giving a reason why.
I'll love you forever if you comply. Please?

I swear I'm not going to make a habit of finishing these things within ten minutes of midnight every week. Really, I promise.

I'll warn you up front: if I have any ability to judge the quality of my stories (I'm not really sure I do; even just by guessing I'd get some right), this is far from my best work. But you know how it is when you're obsessively participating in weekly events; even if you don't have anything good, you've got to show something.
I give up. As of now, I will cease to have opinions of my own writing. There is clearly no correlation between how well I think I've done, and how well you all think I've done.
