Compassion - thoughtful caring for the suffering of others combined with a desire to see that suffering end - is opposed by fear. I have lots of fears.
I fear that people will see my compassion as "emotionalism" and not as a thoughtful process, dismissing it. I fear that if I am compassionate others - certainly including my children - may become (too) dependent on that compassion and lose drive to do things for themselves. I fear that compassion will be interpreted as weakness and lead others to devalue me. I fear that compassion will be seen as an opportunity for others to take advantage of me. I fear that others will see my compassion and infer a hidden agenda; they will think I am dishonest.
I'm working on it. Part of working on it is writing it out, because sometimes I know a thing but having to form it into real sentences makes my knowing clearer.
