spoiling for a fight- Open RP

The question was like a burst of energy, breaking through my haze of annoyed thoughts. I turned to see who had asked it, just in time to see someone stepping out from behind a tree. I wondered what she was doing there, and why she apparently hadn't come out of the school like the rest of us. Maybe she had dropped out. She really didn't look like the educated type. She didn't look stupid, though, there was something about the way her dark, intense eyes didn't stop moving, taking everything in. And she looked strong. Yeah, she wasn't to be taken lightly.
"None of your business, that's what," I said loudly and somewhat aggressively, repressing a grin, sizing her up. I stopped walking, and the rain started pooling around my feet.
It grew colder and a little darker as more clouds gathered overhead, but that didn't make me want to go home. Since when had I had a conversation with someone who wasn't the housekeeper or a teacher that I hadn't started?

I frowned. She was backing down, just like that? I crossed my arms and tilted my head. I still was curious about what she was doing out of school and how she managed to get away with that.
"Why weren't you in school, anyway?" I said quickly, hoping she wasn't just about to walk away. I continued quickly, "And what were you doing in the trees like that? Spying on everyone?" I took an accusatory step towards her, eyeing her suspiciously. I didn't really think she was spying.

I rolled my eyes. "Very funny."
I turned to keep walking, since the rain was finally starting to bother me as it soaked through the shoulders of my jacket. A lot of the other kids from the school were gone by now, having rushed home.
But really, what was she doing there? Was she seriously just hanging out behind a tree? Maybe she had somehow gotten her hands on drugs. She was oddly expressionless. Or maybe she was just weird.
My curiosity got the best of me and I turned back towards her before I had even taken a full step away.
"Really, though. Do you just like, hang out behind trees?" I tried to sound casual and suave, a lot less curious than I actually was. I laughed a little.

I frowned. Was she seriously just going to ignore my question like that?
"Uh, yeah. How do you know that? And you didn't answer me."

I remembered Matt, vaguely. So she was one of the Young kids. Studying her face, I could see the resemblance, I guess. I rolled my eyes again. "I doubt he was smart enough to pass anyway," I said carelessly.
"Examining the tree?" I repeated. I laughed. "Wow, okay."

I watched her narrow her eyes and step closer. I suddenly realized how much shorter she was. It made me take her angry expression and her whole demeanor a lot less seriously. I chuckled-- and stopped when I saw her hand on her ax, the handle darkened and the blade slick and shining with rain. I glanced from the ax, to her face, and back. Okay, maybe I could take her seriously.
"Talk about my brother like that again and I'll make you my next tree," she said, glaring up at me, and I had stopped smiling, my eyebrows raised skeptically, my mouth an intense slash across my face.
"Suuurrrre you will," I said slowly, and as I realized the absurdity of the thought of this short girl attacking me with her ax cause I pointed out the fact that her brother's an idiot, I smiled again, starting to laugh. She was crazy.
"Okay, fine, come at me, kid." I spread out my arms mockingly, taking a step back. "I'm allll yours."
