Am I ruined?

OK not a great night for training due to the intense migraine. Just then the son comes home--he had seen a recent movie involving MMA fighting so he is all jacked to spar with Dad. So he tries to drop me by going for my legs-i grab his arm; twist; lock; bar and to the ground. He says Do you Know any arm bars? I just put you down with one--he say's that wasn't a bar? ok i grab his arm , do a sort of figure 4 lock and drop him. his response? why do you have to be so rough all the time--you have no control!!! OK I always felt i have great control-the problem my son always complains about is that i do not always distinguish practicing and the real thing. My favorite martial arts book (my Bible of martial arts) is "a book of five rings--miyamoto mushashi talks about when training your attitude should not distinguish between practice and real life(i am not saying not to work with your training partner) but i train with that type of attitude. sorry son!! So am i ruined? meaning unable to control myself- maybe --i suppose it depends on why we train in the first place--i want to survive an attack--not so concerned anymore with tournament or sport--when the Sh*t hits the fan in real life i want survive-not practice. Do you think your attacker wants to work out a few moves or practice? We train for real!!!
