I wanted to explore the complex relationship that Gokudera and Lambo have and here's my result. I dont think it's particularly exceptional so far but I'm hoping it'll at least catch your interest for now. I have no idea how long this is going to be but I'm looking forward to writing more about these two.

WARNING: Lambo is extremely annoying in this story lol. He seems more immature as a seven year than he did when he was 5!

I really dont know how people will react to this story but I hope you'll give me some feedback. UMA's are to blame for any grammatical errors!

Unfortunately I do not own the characters in this story or the manga. If I did the whole thing would be about Gokudera XD

CHAPTER 1- Stand. . Class is in session!

"FOR GOD'S SAKE WILL YOU JUST SHUT THE HELL UP AND LISTEN!"

A powerful bellow echoed around the halls of the Vongola base, accompanied by a short silence eventually broken by the shrill giggling of a slightly hyperactive child. No one in the halls seemed to pay it much attention, they merely carried on with whatever duties they were performing, as if it was the absolute norm. They didn't even have to ask who did the shouting and who did the giggling, it was all part of a practically daily routine.

Where Gokudera and Lambo were concerned, this was just another normal day in the Vongola base. Shouting, screaming, bellowing, Gokudera did it all, until his voice was hoarse and his throat was sore with the effort. Lambo? Well, he was just the same as usual, responsive in all the wrong ways. He had turned seven that year but he still had the attitude of a mischievous, and more often than not, annoying five year old. They rarely talked to each other without one or the other shouting, Whenever they were in the same room as each other something was bound to set one of them off.

Tsuna knew that well, he'd known both of them for over three years after all.

So why am I the stupid kid's tutor all of a sudden? Gokudera asked himself.

Gokudera had practically pleaded with the tenth to find a replacement tutor, there were an abundance of scholarly candidates within Vongola after all. But Tsuna had forcefully refused. He strongly stood by his idea and refused to budge, much to Gokudera's dismay.

It was very unusual that he was so opposed to an idea that came from the boss' mouth...but it was Lambo after all. Teaching Lambo calculus was like trying to teach Philosophy to a goldfish, practically impossible.

Battling Varia, fighting Millefiore, that was easy. Trying to get Lambo to sit down quietly? That's where it got difficult. Lambo had always been an excitable child and Gokudera had hoped that as the years passed that he would eventually mature. He had seen that Lambo had changed when he was fifteen...so why was it so hard for him to hurry up and grow up? What happened to him that caused him to change, and where was it when Gokudera needed it?

He peeked a glance at Lambo through his long fingers, saw him bouncing about so carefree and sighed wearily. It was going to be a long day. Gokudera attempted to reason with him once again, and began to speak in a softer tone.

"Look, Lambo, we really need to get this done by 4. I have a meeting to attend, remember? So can you sit down and listen please?"

The tone he spoke in was such a strange one for Gokudera to use that Lambo immediately began to quieten down. The young boy looked at the older man with suspicious eyes, raised a pitch black eyebrow and gave a little arrogant sniff, before once again falling into deep fits of laughter.

"Gyahahahaha. What the heck is wrong with Stupid-dera? Can you sat down and listen please Lambo-sama? Gyahaha".

Gokudera snapped. He threw the papers he was holding aside and started to shout once again.

"STOP MAKING THINGS UP! AND IF YOU'RE GOING TO COPY ME AT LEAST GET WHAT I SAID RIGHT YOU STUPID COW! IT'S SIT DOWN NOT SAT DOWN!"

Lambo continued to laugh childishly and Gokudera was about to start another loud rant when there was a quick knock on the door. Gokudera turned almost gratefully toward the distraction, gathered himself and opened the door. He came face to face with Tsuna, accompanied by an ever smiling Yamamoto. Tsuna was wearing a nervous little smile on his face and his thin brown eyebrows were raised questioningly, while Yamamoto was wearing the same innocent grin as he always did. At the moment they were the last two people that Gokudera wanted to face. He'd finally accepted the task of tutoring Lambo and he didn't want to let Tsuna down.

Gokudera unconsciously gave his leader a sheepish smile and Tsuna's face fell somewhat.

"That bad huh?"

Gokudera frantically shook his head, eventually saw that he wasn't fooling anyone and gave a resigned sigh, Lambo's laugh still echoing loudly in the background.

"I cant get him to sit down, shut up or listen. He's like a little kid!"

"Well Lambo is only 7...so technically he is still a kid Gokudera", Yamamoto interjected.

Gokudera raised eyebrow in response and clapped sarcastically.

"Thanks so much for that vital information. I'll keep that in mind, but that isn't what I meant. But don't worry Boss...I'll get through to him somehow."

Tsuna gave his right hand a slight pat on the shoulder and turned to leave

"OK. Just don't hurt him. I know you'll manage to grab his attention somehow, you are one of the smartest people in Vongola after all".

A slight smile tugged at Gokudera's lips. It was a pleasant feeling, being complimented by the man you respected so much. But more than that, Gokudera knew that Tsuna had challenged him, he'd learned a few tricks from Reborn after all. Tsuna gave a nod of farewell and turned on his heel, walking in quick, long strides. Yamamoto was quick to follow after him after giving Gokudera a friendly thump on the back. He could hear Gokudera silently cursing his strength as he walked away and gave a small chuckle. Tsuna heard his laugh and looked back at him enquiringly.

"It's nothing Tsuna, just Gokudera being Gokudera."

Tsuna looked puzzled but slowed his pace in order for Yamamoto to catch up.

"I don't think this will be an easy task for Gokudera. Lambo has a certain way of riling people up after all".

Yamamoto continued to grin, his hands behind his head as he walked alongside Tsuna.

"I have a feeling that Gokudera and Lambo will surprise us, just you wait. Gokudera's not stupid, he'll think of something", Yamamoto said with a knowing look.

Tsuna contemplated his words and then gave a slight chuckle of his own.

"You're right. You know Takeshi, sometimes you sound like a young old man. Maybe you're actually the wisest of us all"...

Yamamoto gave a surprisingly mature smile, which completely transformed his face. He looked confident and intelligent, until the serious smile was completely absorbed into an enthusiastic smile.

"Nah. It's just that I trust Gokudera to get things done, that's just the kind of guy he is".

Tsuna smiled. His reply to Yamamoto however was drowned out in another bellow from Lambo's room.

"Yeah...but its how he's going to get it done that worries me..."
