here is my first entry to your challenge. Im not to happy with the out come of this one >.>
This is based of from, two close friends I had, I knew this one guy for a long time, and met his girlfriend shortly after him. I was very close to him, thought of him like a brother more then anything, she one day thought I was like in love with him, freaked out and won't talk to me anymore, and I can't talk to him either. It was a very bad feeling to lose two of your close friends, and to have this one girl not trust you or whatever anymore.
It happened like two years ago I think, but still I do miss them.
