You think the disparity of force was such you'd be justified in cold cocking a middle-aged woman under at least some influence of alcohol? I'm not a large, brawny type by any means but I don't think I'd have felt I was to the point of play knock-out with her. If you two genuinely are, and aren't just talking some ******** bravado, I really feel for ya.
Your pity is not needed nor wanted in the least.
