Selina couldn't help it, not back then, definitely not now, especially not now. You're growing and being a teenager is hard, she just wasn't prepared for how hard it was going to be. Sometimes she feels you're worse than Bruce's bunch.
"Look, I know. I know." She repeated herself as you continued to go on your rampage, she knows, you don't have to remind her every time you two disagree on something. She's not your mother, it doesn't matter that you're the closest thing she has to a child that isn't Bruce kid already. The same way she's the closest thing to a mother you have had since yours just up and left.
Well not exactly since you where a street kid, one which she grew quite fond of, though it wasn't until two years ago when she finally took you in, nothing too official yet. She'd like go adopt you yes, but she's still working out kinks with you. She feels like she hardly knows you, you had one good year and then you switched.
She doesn't understand why but out of nowhere or maybe she just wasn't paying attention as she should have, but you weren't her little kitten as she'd affectionately called you from the day she first met you until fairly recently, regarding suddenly you refused to speak to her, you argued with her about everything
"I really, really am trying to understand and reason with you, but I can't if you don't talk to me." Selina said when you finally stopped to give her an opportunity to speak. She feels helpless when arguing with you over this because you don't tell her anything anymore. Is it someone hurting you? Are you making bad friends? What is it? She wants to know because she's worried for you..
