Adolescence
When Peter closed the door to Groot's room, he was fuming.
"I am Groot," He mimicked, rolling his eyes. "The nerve of that kid! I let him live on my ship, raise him from a sapling, and this is how he repays me?! Self centered little fu*er.."
Rocket laughed, a little too loudly from below him. It caused Peter to startle.
"Well, of course he's like that, ya' nimrod. The lil guy's goin' through puberty." The not-raccoon gave Peter a look that said, 'its obvious,' and laughed again.
Peter blanched, then scrunched his face as he planted it firmly in his hands. He began to pace.
"Oh, gosh, what in the he* does that even mean for him?!" He whisper-shouted, looking down at Rocket in exasperation, "Have we even had The Talk with him yet? There is no way I'm taking that one. And think of all the changes, Rocket! Just think of 'em. He's gonna be eating everything! And do you know how moody he's gonna be? I remember what I was like, and no way am I gonna let Groot be like that…" He paused, a look of disgust on his face. "Oh, no, he's gonna be looking at porn and jacking off every chance he gets, and-"
"Woah, woah, woah!" Rocket interrupted, holding his hands up defensively. He looked beyond disgusted. "Do you even know what a plant is?! Asexual, dumb-a*s. He don't even have the parts for that. You're disgusting, Quill, you know that?" There was a pause, and he sighed, his small hands going to his hips. "Worst that'll happen is he'll cry too much, rebel a little bit, and become a grade-a sass master. Seems to me like that's already happenin'."
Quill sighed and scrunched his face up.
"Why can't we just go back to the good ol' days, where all we had to worry about was him drinking from public fountains?"
There was a laugh as Rocket patted Quill's calf.
"Hate to break it to ya, but parenting ain't that easy, Star-Princess."
It wasn't much of a sentence, but it was enough to make Peter groan and do a little mock-sob as he ran his hands once more over his face and walked away.
"Can't wait till that little he*ion is an adult again."
Rocket simply laughed, knowing that this was simply Quill getting a taste of his own medicine.
Before he could depart, he heard the tiny screech of the door being open and the light scratching of bark against the wall. The woodland creature looked up to see Groot, standing at about 5'2", peering out of his room, his lip almost quivering and his eyes wide.
"I am Groot." He said softly, his voice cracking mid sentence in a way that made Rocket smile. The Floral Not-Quite-Collosus looked down to his feet and twisted his fingers in a vine sprouting from the other arm. Rocket laughed a little.
"What? Why would he hate you?"
"I am Groot. "
"Well, yeah, you were rude, but that's what kids do, y'know?"
Groot still didn't look satisfied.
Rocket patted his leg.
"We love you, buddy. He ain't still mad at ya, and I sure as he* ain't. Now quit yer bellyachin'." The mammal paused for a moment as Groot gave a little smile and began to close the door. "And get a hair cut, ya buffoon!"
