Big sister or pendulum?

I guess being the oldest of 8 siblings may carry some responsibilities. Or maybe just being a sister has more to do with my situation. I love all my brothers and sisters very much. Not that every moment of our younger years was peaceful, but I am tremendously sad that distance, and personality conflicts seem to cause that illusion of the golden days of childhood innocence to disentegrate. I look back and just wish for the days when all there was to fight about was "did you wear my shoes?" For now, I am given the role of peacemaker. I have two sisters in particular with whom I am close, both geographically, and emotionally. They are unfortunately very much alike, and seem unable to co exist in the same zipcode. They both have legitimate gripes about the other, and to me both sides make total sense when presented individually, but together it's like I am trying to listen to a latin lesson in which I see the lips moving in English. That line I just wrote actually makes no sense at all, but I know what I am trying to say if nobody else does-haha. I just want to scream sometimes and just say "why can't you see what I see?" Or better yet, "why can't you fix your own problems and let the her fix hers?" They make me crazy. So all I can do is present my own spin to the story, and give my thoughts, and hope it does some good. The beauty of being the oldest is you have nobody to impress but yourself. And I don't feel like I have to answer to anyone younger than me for any of my actions. I don't feel that rivalry. Oh...the DRAMA....!! Makes things pretty interesting.
