Who is right? Who is wrong?

When I was in the 9th grade, I hung out with many people who some may say were drama queens and kings. Honestly I never really got into their business until one day a friend of mine said something to me that struck a nerve in my body. They basically said " Oh well Marlayna said it", those few words started this huge argument between me and my truest best friend. She thought that I was the one who was talking to her friend and was trying to break their friendship up for good. No matter what I said, my friend believed the other people over me. So after about a week passed by I just stopped talking to them because why should I surround myself with people who think that I am a liar? Why should I be the one to take the blame because I spoke my mind? It took about a year and a half for my best friend to find out that it was her so called friend that started the drama. I learned from that moment on to watch what I said to people because they may change my words and put a twist on it just to make themselves look better .
