If someone behaves negatively towards you, it helps to remember that he or she is a human being like you and to distinguish between an action and the person who does it. If counter measures are needed to prevent someone doing harm, it's always better to do it with a calm rather than an agitated mind. If you act out of anger, the best part of your brain fails to function. Remember, compassion is not a sign of weakness.

-- His Holiness the 14th Dalai Lama
