There's Always a Story

Okay so I just found out part of what happened to Kira Harley in "Modern Day Beauty" that makes her so cynical. I know, what do I mean I just found out? Well I didn't really know about it until it showed up on the paper so cut me some slack.
Her mom left when she was eight. More details you say? Gladly;

NEED TO KNOWS: Okay so she's got a twisted ankle and she just stormed out of the cafeteria. She's making an effort not to appear to be limping and she refuses to use a crutch.

"It's swollen," East stated from my left.
Startled, I looked over at him and let my pant leg drop, getting to my feet as quickly as possible. "Thanks for the observation," I retorted sarcastically, leaning casually against the lockers in an attempt to make it look like everything was fine.
"It's never going to heal if you keep walking on it," he said flatly, looking me in the eye.
I hated that look at once; it was like he could see straight through me, and I didn't want anyone to see that. In response, my body stiffened, as if trying to hide the parts of me best left undisturbed. "It doesn't need to heal, there's nothing wrong with it."
"Look," he told me, irritation flickering across his face as he started to walk towards me. "I'm sure if you ask, the nurse has a crutch or something."
"I don't need one," I snapped, straightening from the row of lockers. If I didn't put any weight on my right ankle, he didn't notice...I don't think. "I'm perfectly fine. I don't need any help."
"If you'd stop being so stubborn--" he began angrily, but I didn't hear the rest, I didn't even see him.

"If you'd stop being so stubborn, you'd see that this is for the best, Kira," Mom informed me coolly.
But I didn't know how to stop. I didn't want to. "I don't need you," I told her, my voice wavering as my eight year old eyes filled with unshedable tears. "I don't need you so just go!"
"You're too young," she informed me. "You just don't understand where I'm coming from."
I understood where she was going though. I may not have known exactly why, but I knew where she was going. She was going away from me. She was leaving me. I refused to shed those tears and I refused to beg. If she didn't want me, I didn't need her. "Just go," I whispered, looking away.
"Kira," she tried gently.
"Leave!" I shouted, turning hardened blue eyes on her. "I don't need you."

"Kira!" East snapped, shaking me. I blinked, and then my eyes focused and hardened. "Were you even listening to me?"
"I don't need help from anyone," I snapped, jerking away. Gritting my teeth, I suffered the pain and hurried away.

So it has to do with her mother, see? I was thinking her father since she seems to have the issues with guys, but I've got some tricks up my hoodie sleeves. Toodle-oo!
