I too was taught to treat others as you would want yourself to be treated. It is very good advice that was handed to me by my mother.......but in dealing with teens in my job and others that have passed through my life I have found that this does not work.....sometimes it is best to give them back what they dish out. To mirror their behaviours, so to speak. It has at times been very successful for me and my dealing with difficult people. Sometimes when you walk away from a problem with how your being treated and "turn the other cheek" the other person can feel empowered over you and continues their behaviour and then you have a real problem on your hands.
