Aggression

Dear friends,
i have a real problem with aggression. I try to avoid aggressive people in my life. Being retired makes it easier but every so often I come across an aggressive person. They are so out of control. I have never been an aggressive person and have retreated or gotten angry rather than aggressive. Are you an aggressive person? Do you have aggressive people in your life? How do you handle them and their aggression?
lots of love from susan in australia
