Why can't everyone just get along????

I am a person who hates conflict, so I try to avoid it at all costs. Sometimes, though, I obviously can't avoid it, and so then I have to deal with it. Over the past few months there has been some drama within a group of my friends, and until recently I have been able to avoid getting involved. You see, about a month ago a nice sized group of my friends all planned a fun trip to King's Island, I think altogether it would have been seven or eight of us. About two weeks ago, some of them got into a fight, and they all came to me to be the "mediator" I guess you could say. Being the mediator of arguments can be one of the most frustrating positions, and after about a week of being the "go to" person, I had to tell them to leave me out of it, and that may have caused me more problems than it did to help keep my sanity.... The big King's Island week-end trip has finally come, but only a few of us are going because some people are not talking to others, and now my younger sister is giving me the silent treatment over going. At first I was tempted to back out of the trip because the person I was mainly going to see, a very old friend of mine, almost had to back out of the trip too, but when she said she definitely was going I decided to go afterall. At first I felt bad about my sister not going because she could not get off of work, but lately, her attitude towards me has made me think twice. In fact, I am more excited to get out of town for awhile and away from the drama because of it. It's times like this when I want to just have some sort of magic power and go *poof* and make everyone get along and stay happy. So since I don't have that magic power, to save me from excess stress I am going to go on this week-end trip and hang out with my friends and have fun, because I've gotten to the point where I am so over it all.
