' you kissed him i'm not stupid i have eyes' then she was gonna punch me but i grabbed her arm before she could and punched her then threw her on the ground then her girls came and my crew of girls came and it was this hole fighting ring with my crew against her crew and me against her then the hole school gathered around us and was all like 'FIGHT! FIGHT! FIGHT! FIGHT!' and there was blood everywhere and all over the S.L.U.T.S face so obviously i was winning HA!! then the principal came out and blew his whistle and christian and his friends had to break us apart it was horrible when i saw the floor blood everywhere then i heard my mom yell my name right then i knew i was in deep sh*t. when i got home my mom was furious my brother was all like 'hey sis i heard you got in a fight and won oohhh yeahhh thats my sis GO JESS!!!' christian started laughing and so did i but then i rememberd my mom was in the room so we stopped laughing and my bro whent to his room with christian so i could talk with my mom she said that i'v already been expeled from three schools and now this she said that i'v been in over ahundred fights witch was true and that this was the worst fight yet just then she got a call from the school nurse and she said that i left the S.L.U.T. with lots of bruises and two broken ribs for kicking her and one broken arm.my mom looked at me and said that she couldn't deal with me anymore so she said that she was going to send me to my dads friends house great just my luck.he has three sons that are always hitting on me yuckk!!! i couldn't move i would be away from christian and we'v been together for 3 years.i yelled at my mom and she slaped me right across my face.she was like 'look at what you'v done to that poor girl at school!! look at how many times you'v been ecxpeled!! look AT WHAT YOU'V DONE TO THE FAMILY YOUR A BAD INFLUENCE TO YOUR LITTLE SISSTER AND YOUR BROTHER!!!!! she yelled when the guys heard that they all came down stairs((BTW christian had his friends over and they where with my bro in the room))in a hurry i was still on the ground with my cheek bleeding from the slap my mom gave me.christian took me to his house and his mom helped with my open cut on my cheek his mom was like a second mom i could always count on her and his dad.the next day at school i saw the S.L.U.T. and her girls and my girls where with me we looked at them and they hurried out of the hallway they where scared of us now hahaha.later on i was at my house packing to go to my dads friends house for two years agonizing.when i finished i said my goodbyes to my friends christian my perfect bf who i probably would never see again all of his friends said bye to my sis and bro but didn't say bye to my mom cuz she's a b*tch.said bye to everyone one last time and met up with my dads friend and his sons here comes the moves,complimenting,them hitting on me,and much more.all because of a stupid fight.i looked at christian and he looked pissed because he knows they hit on me i ran to him huged him and gave him a kiss and the last thing i said to him was ill never forget you i love you and after that i was gone for good.HELP ME I WAS STUPID FOR DOING WWHAT I DID AND I REGRETT IT SO MUCH CAN SOMEBODY TELL ME WHERE I WHENT WRONG AND HELP ME GET BACK ON TRACK SO I CAN GO BACK HOME AND SEE MY FAMILY AND FRIENDS AGAIN ESPECIALLY CHRISTIAN.
