Can you forgive?
Most of the time a bully will forget who they hurt. It is so unimportant to them that it vanishes from their mind. But your right - if we dwell on things then it's just us we hurt. A few people in our circle got into that chain of thought and it split us. Now most have moved on and made up and are friends once more. But a few still harbor that pain and they won't let it go. It's sad to me that we do bad things to each other, but it is more sad when we can't move past it and just live free of that bad moment in time. A person will hurt us once and we will hurt ourselves many times holding on to the anger.
