"Hello, Sweetie. I'm glad you were willing to come over on such short notice. There really is something we need to talk about." 

Sweetie, my girlfriend, looked very nervous for some reason, but she walked in and stood next to my living room table. 

I smiled, and I walked over to my 100% room darkening curtains. "The reason I asked you over here tonight was–"

"Wait!" Sweetie interrupted me. "Before you say anything, I need to do and say something!" Sweetie hopped up onto my table. Then, in an array of glittery sparkles, she shrunk in size, and wings appeared on her back. 

"As you can see, I'm not human like you are. I'm actually a fairy. But, I've been living among humans, trying to learn more about them. They're always making wishes of us, and I wanted to know why. But, I've learned all I can on my own; now I want to learn more. Because we've spent so much time together, I've fallen in love with you, and I want to grant you your wishes. Fairies live to make others happy."

"So, that's why I am the way I am. Will you be able to accept that, and accept...me, or rather, us?" My girlfriend stood before me, holding out a silver ring on her outstretched arms. Yes, I said "on" her arms. My girlfriend has just revealed to me that she's actually a fairy. A freaking fairy, with wings, and magic, and everything! It would've been cute, if her clothing had changed sizes with her. Instead, the only thing keeping her dignity intact is the silver ring that she's trying to give me. 

Well, nertz. Now I'm not going to be the first one to do my big reveal. I speak up anyway.

"Um, I absolutely accept your proposal, Sweetie, but I have to insist on a gold ring."

I never was one to beat around the bush. That was one of the reasons Sweetie loved me so dearly.

Sweetie tilted her head and raised an eyebrow. "Why's that, Mister Honeybuns?"

"And I thought I asked you to use a different nickname for me. It isn't manly! Anyway, this is the reason. I don't think you would anyway, but I want to tell you that there's no need to fear what you're about to see. I'm in full control at all times, unlike what happens in those horror stories."

And with that, I fling open the curtains, revealing the full moon in all its silvery glow. Immediately upon seeing it, my change begins. I grow taller, fluffier, and toothier. This used to hurt, but after fifteen years, I've learned proper breathing and stance techniques. You'd be amazed at how many werewolves forget to breathe during the change. Changing body shape, size, and DNA requires a LOT of energy, and in a mammalian type of creature, where do you think that energy comes from? Oxygen, of course! And where does oxygen come from? Breathing, of course!

Anyway, all this to say, I basically go KER-FLUFF without grimacing, growling, or being grumpy afterwards. And by wearing some oversize clothing on full moon nights, I still have my dignity intact, too. 

"Now, as you can see, I had good reason for wanting to talk." I give Sweetie a goofy, toothy grin. "It seems I'm not the only one who wanted to reveal a big secret tonight. I hope you can understand and accept me, too. And I hope you can understand why I have to insist on a gold ring instead of a silver one."

Sweetie dropped the ring and dropped on her bottom, laughing. "And here I was, worried over nothing! Whoo! Hahahahaha!"

Sweetie took a minute to compose herself, and in doing so, realized her state. A quick flash of sparkles later, and she was wearing a cute one-piece dress. 

"I see what you mean, Mister Fuzzbuns," Sweetie teased. "And I guess the irony has struck me again. So much for learning more about humans by being with one."

Sweetie flitted up and landed on my nose. "I guess I'll just have to learn about werewolves instead, for a while."
