When I was that age, I wore sweatpants every day. I didn’t start wearing deodorant regularly until Qadgop told me I smelled like a goat. (He was right, unfortunately.) I didn’t shower anywhere near often enough. I couldn’t really run or play sports anything other than ineptly. And even worse, I did very well in all of my classes. The predictable happened. It sucked. A lot.
And you know what? I got over it.
I grew up and mastered Fashion and Cleanliness. I assume a few of the people who tormented me eventually became decent human beings, but I don’t really care. It’s long over, and it doesn’t do me any good to focus on it. I have a life now, and that’s much more important.
START, I’d mentally categorized you as “annoying and a bit of a jerk,” but regardless of popular opinion, I think you really ARE sorry.
I think you deserve how she’s currently treating you, but I don’t think you should just sit back and let it happen. For one thing, it’s not good for her to be doing this to someone. If she gets too used to acting this way, it’s going to change who she is for the worse. Hatred just isn’t healthy, for anyone. Even if it is deserved.
Apologize, and I mean really apologize. Of COURSE she didn’t accept your apology in the 7th grade, sheesh. That doesn’t excuse you from apologizing now. Tell her how you were an absolute asshole in middle school, how you can’t even imagine how much you must have hurt her, how you feel really guilty about it. Ask if there’s anything you can do to begin to atone for it. If that includes never going near her again, do it. In fact, suggest that. It’s a good idea, regardless. And whatever else atonement includes, within reason, do it.
And after that, if she keeps dishing this stuff out… Say something nice. Every time. Tell her her hair looks good or congratulate her if you hear she’s done well at something… or even just say “I’m sorry”. Not “Geez, sorry!” or “I said I was sorry!” just a sincere “I’m sorry”. Every time. That’s a lot closer to real atonement then just trying to ignore her, you’ll have to work for this. I doubt she’s going to become your best friend… but she may end up not hating you, and she’ll probably stop sooner.
If you want to talk to someone who understands what you did to her from her perspective but who doesn’t want to disembowl you, email me or something.
