I Am Not - Regret
I never got into a fight growing up and I have always regretted not defending myself from childhood bullies. In seventh and eighth grade I had a classmate named Heath who would hit me almost every day in school. Heath was more muscular and taller than I was so I was always frightened to hit him back. Around this the same time, there was also an Irish-American boy in my neighborhood named Trey who would taunt me and threaten to hit me every time he saw me.
To this day, I continue to regret that I did not punch them both in the face. I regret being such a coward and being the passive victim. Perhaps these bullies would have beaten me up, however it is entirely possible that my act of self-defense (or preemptive strike in the case of Trey) might have served as a deterrent in the future.
I plan teach my son never to act as an aggressor. However, if someone punches or hits him, he should know that he should respond decisively; forcefully enough to make his aggressor reconsider doing it again. While I cannot change the past, I can attempt to change the future.
I can teach him not to be the passive victim that I once was.
Afterthought: Looking back, psychologically I can now understand why my heroes in my teenage years were the fighters of the Irgun Zvai Leumi.
