Old people do and will always do whatever the hell they want to do. Simple fact. It's a rule. You get to be 65, you just get to quit caring about what people think about your actions. While I'm never an advocate for assaulting a woman, considering the circumstances, I don't think he was completely unreasonable.
Common sense should take over at some point in a situation and she used less than he did. Saying something like "don't assualt people, you'll probably last longer" isn't the most philisophical thing to say.
Maybe you should use common sense where you piss and you'll last longer.
