I've had a couple: First: When I was about 3 years old, my cousin pushed me into the canal behind our house. I can still remember how green everything looked in the Gulf water, and the crab scuttling past my face as I lay on the sandy floor of the canal. Second: When I was in college, a man pointed a gun at me and threatened to kill me over a girl I didn't really know. He had been harassing her and she asked me to stay with her as she waited for her ride home. What troubled me about the incident was that I wasn't frightened; I got MAD. Probably not a healthy response.
