While as any one knows fights were if you want to call them this way "arranged " while in school, you know the typical "meet out by the park, oe behind the library after school or 3 0 clock" but other than that some fights like being at a party or a bar just come about no pre arranged like you would do for a IRL rules match , whenever one of us was going out usually if not all at least another sister was there and if a fight broke out like I was saying the sister not involved was there making sure it stayed one on one or no one was jumped by 2 or more, but No we never had a mass meeting like your asking.
The one girl I fought 3 times in HS her family and ours just never got along, sheand I were the bustiest all through school, and we could have passed for sisters , but they lived in a less desirable end of the town so not many "hung out " with her (she had no sisters) a few of her friends were the slug types in school didn't care if they passed or failed and more often than not suspended or cut types, never knew why a girl who had a lot going for her looks and book wise chose that way but it was her decision ,anyway her and I if not asked if we were sisters were often compared and the fact I never bothered with her i think pissed her off, I was a cheer leader , dated Jocks type, so in jr. year her and i had a quick slap and hair pull session in the bathroom once as it got heated we were stopped, i had her ass on the floor, Sr. year we went at it again this rtime it was a lot more intense I kicked her ass but she fought hard, right before graduation on Sr. cut day totally unplanned at least by me we ran into each other at a tail gate party and fought I scratched ehr face after she scratched by chest then i slammed a right fist into her chin and she dropped, it was over, then her and I had our famous last run in after HS i was dating my then fiance now hubby he was home from boot camp snd we went to a bar to see friernds I was in the ladies room and she thought it a grand idea to approach him and try to flirt he gave ehr no attention and upon my return I told ehr to take a walk, she tugged my hair from the back as my back was turned I spun around and smacked ehr face, the bouncers were on us before more went on, so I told her to meet me at the school football field she did and we settled it again, was a rough fight but in the end she was face down in wet grass and goose crap yes we both had a torn top and plenty of hair ripped but that was my one and only time my sisters weren't there just my fiance.
