Sorry I forgot to answer your questions, though I am unsure as to their pertinence in this conversation. The answer is 0. Zero. To all. No street fights. No training to fight or kill. No combat arts classes. I have zero desire to learn or use these skills.
And now I’ll wait for you to tell me that because I haven’t been in street fights or learned Ju-Jitsu, I don’t get to choose when I’ll engage in conversation with men I don’t know.
