Negativity is a trait, not someones identity. A persons true nature can be obscured by clouds, but, like the sun, it is always there. And clouds can overcome any of us. We have to understand this when we deal with people who exude negative energy. Just like we wouldnt want someone to judge us by our worst moments, we must be careful not to do that to others. When someone hurts you, its because theyre hurt. Their hurt is simply spilling over. They need help. And as the Dalai Lama says, If you can, help others; if you cannot do that, at least do not harm them.
