A friend's tale of woe may have you taking out the tissues and formulating a revenge plan, but hold off on moving forward, because there is more than one side to every story. What you know right now is only part of the picture, and new information will be coming later that could change how you feel now. Unless you want to be left with egg on your face, avoid making any moves on behalf of this other person. Let them fight their own battles and learn their own lessons.
