"Hey Marceline?"
"Sup Finn?"
"Why am I 'too young'?"
"Huh? Oh. Been talking to Bonnibel lately?" Marceline asked.
It was a quiet evening. Just the two of them jamming at Marceline's house.
"Kind of," Finn replied.
"Still crushing on her?" she asked.
"No!" Finn replied emphatically. "...maybe."
"Wanna jam about it?" Marceline began idly plucking out a bass line.
Finn sighed, "I sort of did already."
"The Doorlord thing?"
"Yeah. And after that, we never really talked about it."
"'What are you to her?' Well, Bonnie was always kind of a stick-in-the-mud. Yeah, your age is probably a hangup."
"But why?" Finn returned to his original question.
"Its this kind of idea from a long long time ago. How should I explain it?" she pondered, "Okay, let me give it a shot: You're still growing. Not just getting taller and buffer and all that stuff, but also in your brain. Do you remember yourself two years ago?"
"I guess?"
"Don't you think the you two years ago was really kind of dumb? He said and did things that you find embarrasing now?"
"Yeah?" Finn couldn't help but remember some of those things.
"Two years from now you're going to think the same thing about the you right now. And two years from that, that you will think the same thing about him. That's just life. And unlife."
"Huh."
"We DO get less dumb as we grow up, but it takes time. You can try to rush it, but you just end up jack up your brain worse. So when people say 'you're too young' they mean 'I don't want to be the one to jack up your brain'."
"Man, my brain is already all kinds of jacked up. No one says I'm too young when I do hero stuff."
"Yeah, that's true," as Marceline reflected, she continued to play, mostly to keep her hands occupied, "Its kinda unfair. But thems the breaks."
Finn frowned. "Come on, give me some credit."
She chuckled. "Okay. How about this? Lets pretend we're boyfriend and girlfriend for a second."
"Uh, alright," Finn blushed at the sudden turn in conversation.
"So, we'd go on dates, right?"
"Yeah."
"And hold hands," Marceline took his hand into hers and laced her fingers between his. Finn flinched a bit at her cool flesh and the sudden intimacy.
"Uh-huh?"
"And do kissy stuff," she drew him in by his hand, and kissed him on the cheek.
Finn attempted to conceal his rising discomfort.
"And get all touchy-feely," she released his hand only to pull him bodily into her. Finn stiffened.
"And maybe," she leaned in to his ear, so he could feel her breath "if we're feeling really romancey, we could..."
She whispered a few choice sentances, each turning him a deeper shade of scarlet.
"Oh, and that's just the tip of the iceberg," she seperated from him entirely, the intimacy evaporated.
Finn's expression was one of pure horror.
"People actually do that! That's sick!"
Marceline cackled in amusement. "Well, some do. I'm not into that, personally, but hey, I'm willing to try anything once."
Finn regarded her with a disgusted look.
"There's no rush to grow up," she patted his head, "You're not ready for that stuff yet, and that's cool. So... you get me?"
"Well..." Finn forced some of the more salacious thoughts out of his head. "...I might be ready for some of it."
"Ahahaha!" Marceline playfully slapped him on the back. "Not bad Finn. Not bad."
"Hehe. I try."
