Never pick a fight with an old man. He won't stand toe to toe with you. He will just reach into his pocket, pull out a gun and kill you.
That is simply because, An Old Man does NOT have time For a Young Mans, BS. He has already "Been there, and Done that"... and knows it is better to just put the idiot out of his Misery, humanely......
Time was a good choice of words. As I've grown older I've realized that "fist fights" and brawling are a young man's game; however, maiming another is quite a different subject.
Leave it to youth and inexperience to bring a knife to a gun fight. My daddy put a rattlesnake in a mans pocket and asked him for a match, and my daddy was the family WIMP.
