To expound on what Mike is saying... If she's drunk, YOU don't have to do a DAMN thing for HER! If she needs you, she'll have to straighten the hell up. When you stop the Train, it stops! She will figure out really fast who's lost control and that's HER!
When she's running her lips drunk off her ass about this, that and the other, just look at her, smile and say, Well, it's been a long day Honey. I'm off to bed, I have things to do at the office or go out to the range. Whatever it is you are about to do. Short and sweet man. Get out of her way!
When I did this, it was the best thing I'd ever come across! He knew that the gig was up! He wanted to know who I was talking too and what I was reading. I told him NOTHING!!!! It was non of his business since his alcohol was clearly none of mine.
You can not argue with a drunk snood. You will lose every single time.
