In the NaNoWriMo forums there was this Dear Author thread where you could write a letter from your characters. So I decided to give it a go and these happened. They were quite fun and give a nice little insight into Vi and Windy's different personalities.
Enjoy the future hints for 'Until That Day...' ~ (obviously, don't read it yet if you don't want spoilers)

Letters to the Author

Dear Nattie/Writer/Author/strange person running my life...

First off, um, this is awkward. I'm not sure where to really start. I never expected to be sending you a letter. Uh, I guess I'll first say thanks. Thanks for allowing me to be more than just a dream idea that you could have abandoned. I've seen some of the other characters in your head trying to poke at your thoughts for attention. I'm glad I'm not one of these. They look so sad... So I'm glad to be alive, but you don't make that easy. Can I stop being in dangerous situations? You know I don't like those. I mean, was it really necessary to have me kidnapped and tortured? Couldn't we have done without that? I know my boyfriend would have preferred for it to not have happened either. And, we'd rather not have that fight you have planned...

Speaking of things not happening, could we, maybe, you know, not kill off my friend? They're like one of my best friends. Do they really have to be murdered? And then have it blamed on me?! Really? Please... Couldn't there be another way to find the real troublemaker? You know, without death? Haven't you put me through enough?! *sobs*

That being said, I'm excited there might be future stories. Just, please don't kill anyone else... And I know you're excited about that one down the track but... um, do I really have to do that? I mean, going to another universe, one that's a mirror to my own, sounds really scary. Can we just not? I don't understand why you're so thrilled about that... Friends are enemies and enemies are friends? *groans* It already hurts my brain...

From Violetwind.

P.S. Could you please not kill my friend?

Dear Nats,

Hey, girl! Since Vi got the chance to say something I figured I should to, ya know? We are one in the same, after all. You can't deny me!

Ok, since we got that scrap out of the way, how come I don't get more lines! You know I'm, like, always there! I wanna say more! How can you suppress my absolutely, fabulously, awesome, sassy nature?! It's a crime I tell you! What is wrong with you girl? Am I just too much to handle? Seriously, I want in on some of that romance action too. Why should Vi get all the attention? What about me! I know she's the main character blah blah blah and all that scrap. But I made her that! It's my fault she's there! And I never get any credit for anything any more! You know I'm most of the brains in this operation! (since I can't be physical trapped in this body...) So come on, just acknowledge me some more. I provide some much needed sarcastic comments. Seriously, you can't expect Vi to carry this on her own. We both know what she's like. Sure she might have come a long way since we started but, come on. She's no me.

From Windy, aka the Awesome half.

P.S. I'm watching you!

P.P.S When am I getting my own story?!

Around next week or so I should be posting my reply to them. :)
