Title: I Don't Know

Summary: "Has anyone ever noticed that we never celebrate Natsu's birthday? When is it anyway?"

Warnings: This is a Shounen-Ai/Yaoi(BoyXBoy) story, so if you're not into this sort of thing, I don't suggest reading it.

Rated T, for swearing.

Author's Note: Okay, so my birthday is coming up soon(OH YEAH!) and somehow I related that to Fairy Tail. Don't even ask how that happened... but anyway, this story happened! It'll have about three chapters, maybe one or two more depending on how long I make the chapters. Please do read, review, and enjoy!

"WHY DOESN'T ANYONE FUCKING KNOW WHEN HIS BIRTHDAY IS?! YOU'RE ALL USELESS!"

Everyone around sweat dropped.

"Uhm Erza…" Lucy lifted up her hand awkwardly. "To be fair, you don't know when it is either…"

Group-face-palm.

That I really had to laugh at. I couldn't hold it in.

Erza's aura slightly darkened. "You have something to say, Gray?"

Great! She ignores Lucy's statement, but focuses on me?!

"NO MAM!"

"Good."

Bitch. Okay, maybe this calls for some explaining. Look into the flash back… loooook… okay, seriously, just look at the damn thing!

FLASHBACK

.

"Has anyone ever noticed that we never celebrate Natsu's birthday?" Lucy asked out of nowhere.

Everyone around her (Namely Erza, me, Mira and Happy) all stopped what we were doing to stare at her.

"Eh?" Mira said, voicing out all of our confusion.

"In all my time at Fairy Tail, I just realised, that not once have we celebrated Natsu's birthday…" Lucy repeated, while rubbing her chin in thought.

We all continued to stare, until Erza coughed slightly. "What made you think about that all of a sudden, Lucy?"

Lucy, who just snapped back from her thoughts, shook her head. "I dunno, actually. I was trying to remember a few dates and occasions, and I realized I have no idea when Natsu's birthday is… and that we never celebrate it…"

Now that I think about it, she's right! WHEN is Natsu's birthday…?

Fuck.

"Now that I think about it…" Erza started rubbing her chin in thought too.

"AAAAAAAHHHHH!"

I quickly covered my ears as we heard the most ear-cracking scream, EVER! Everyone else in the guild was staring now!

"WHAT THE FUCK MIRA!" I yelled, still covering my ears, along with some others.

"Lucy's right! Why don't we celebrate?!" Mira said all in one go. Damn it, that's why she fucking screamed like that?! I suppose the other guild members got bored and carried on doing other things, ignoring us again.

I rolled my eyes. "Oh, maybe it's because… we DON'T KNOW when it is?" I replied sarcastically.

"Aye!" Happy chirped in. "No one really knows when it is."

Lucy gaped. "But you're his damn cat! How can YOU not even know when it is?!" The blonde pointed a straight finger towards the blue feline.

"It's mean to point fingers, Lushhhy!" Happy stuck his tongue out and ignored her question. "Besides, you're pointing a finger at me? I'm a cat! Your the human!"

Lucy's vein popped. "What has that got to do with anything?!"

"Someone's a little blonde today…" Happy giggled, while pointing towards Lucy's hair.

"WHY YOU LITTLE SH-"

"Okaaaay, moving on." I nervously interrupted Lucy's colourful language. Fuck, Lucy was scary when she's angry! And as if she read my thoughts, she shot me a death glare, and Happy made that weird face he gets when he realizes his safe… for the moment.

"My, oh my." Mira put and finger to her chin and shook her head in amusement.

"Well, now that, that is out of the way." Erza stated, referring to the quarrel between Happy and Lucy moments ago. "Lucy does have a point. Why do you not know when his birthday is, Happy?"

Happy rubbed the back of his head sheepishly.

"Because… well, he never told me about it…" Happy looked up towards all the concentrating stares. "When he explained what birthdays are to me when I was little, I asked when his was."

"And what'd he say?" I asked.

"He changed the subject and told me about all the fish we'd eat when it my turn to have a birthday." Happy said as his mouth subconsciously watered. "He also looked a little sad when I asked, but it's like he just brushed it away."

We all silently thought about this. It's weird, really. We all know Natsu doesn't like to talk about things from the past, but not even his birthday?

Damn it! This is frustrating!

"Hey, you guys." Lucy disrupted our thoughts. "You guys knew him when you were kids, right? How come you didn't celebrate it then?"

It's like somehow we all felt guilty when she said that…

"Well…" Erza tried to reason. "He never told me when it is. Or Gray, as far as I know."

I nodded my head to Erza's statement.

"Natsu was kind of afraid of me as kids." Mira said with a small smile, making us all sweat drop. "So he didn't tell me."

"And Happy's also out, since he didn't tell Happy either." I mentioned, while said cat sat down munching a fish.

And at that moment, Erza's calm side crashed and burned to the ground.

END FLASH BACK

.

And now we're here!

"Where is Natsu, anyway?" Erza asked, as if these few moments before had never happened. Erza really was something else, I must say.

As if on cue, the guild doors burst open.

"OI MINNA!"

"Ah, there he is…" I said matter-of-factly.

The rest of the guild all yelled out their greetings, while some went towards the idiot and others went back to doing whatever the hell they were doing.

"SOMEONE FIGHT ME! I'M ALL FIRED UP!" This same phrase you'd hear everyday, was said again as Natsu stood near the door with that infamous goofy grin plastered on his face.

"Man, does he know how to make an entrance…" I sweat dropped.

Lucy and Mira giggled.

"NATSU, COME HERE!" Seems like Erza couldn't wait to see him! Or kill him…

I shivered slightly at Erza's dark, commanding voice. I noticed Natsu freeze and tense up a little.

"E-Erza…" Natsu gulped as he slowly turned around and walked over to our group at the bar. No use picking a fight with him now, there's only room for ONE of us to die today, and it ain't me!

The other guild members he was standing by also shivered. Yes, this demon of a woman was that scary.

"I have one question for you." Erza narrowed her eyes, as Natsu stood in a somewhat safe distance of at least one meter. You know, just in case things didn't turn out so nice.

Natsu rubbed the back of his neck sheepishly. "What is it?" He asked, feeling slightly less nervous. Only slightly.

"When is your birthday?"

Natsu stood dumbfounded. "What?"

Erza crossed her arms and took a step forward. "When. Is. Your. Birthday?"

The rest of us just sat there watching. I know I wasn't going to interfere, and Erza had the right idea anyway. You know… sort of. We just wanted to know when his damn birthday was!

All Natsu did was stare back into Erza's cold glare. He didn't even attempt to answer. I really wouldn't be surprised if she kicked his ass for that.

"Well?"

And then he did the unexpected.

.

.

"OI NATSU! Where are you going?"

I can't believe he just turned around and walked away! What the fuck is wrong with him! I mean, I was really surprised, but Erza was at a complete loss for words! No one walks out on her like that. NO ONE.

Natsu completely ignored my shout and simply walked out the guild doors, all eyes glued to his back.

A few moments of silence past.

Lucy shifted uncomfortably in her seat at the bar. "Uhm, what just happened?"
