Fighting techniques and things to think about before it comes down to physical violence?

I dont mean things to think about as in, 'Fighting is wrong, talk things out', i dont care who you are or what your middle name is, that doesn't work. I mean things like, 'know where all piercings are and vulnerable spots on the subject, in this case a teenage girl, about 120 lbs., about 5'5, and has ears, eyebrow, & nose pierced.
I am 100 lbs., 5'4, and have my ears pierced. the person at hand has had several conflicts in her past and has broken several bones because of this, obviously meaning she has brittle bones. Any techniques that can enable me to bring her down dispite the difference in our height and weight? Please, note her size and weight, along with the piercings when answering my question, and also give me ways to think about her when she is around and isnt causing me any physical harm, but still picking on me or intimidating me.

Most people are easily tripped. When she gets close enough, place one leg behind her knee and push her shoulder at the same time. Once she's on the ground, kneel on her neck until she promises to stop attacking you.

Dont let her get in range. Punch in the face repeatedly. If you can get her down, DO NOT let her back up and just whoop her @ss.

Good Luck!

Dr. Phils rules for fighting fair....I like them!

.stab her in the eye with a pencil. a long sharp one. preferably a mirado#2. gaurantee it will put a stop to her b/s

the most obvious things are to rip out her piercings first and make her eyes tear up if possible, then give that B**** a shot in the ribs or face. If you don't want to do that.......just smack her nose to make her nose bleed and eyes tear up, then she's all yours. Just don't shove the nose up into her brain and kill her and end up in jail. Hope this helps. Trust me, it'll work. Just go where she is vulnerable.
