On safari, animals get into small "fights" and shake it off like nothing. They literally shake it off, as if getting rid of the energy. We've all seen our pets do this...
Safari animals don't get their feelings hurt, and they don't seek revenge.
Why can't humans master this? In a general sense, is our insistence on holding grudges what is dividing our country and world?
BTW: the next time someone makes you upset, physically shake it off, and see how you feel.
