Yeah, I have those days, too. Days where you just pray that some random stranger will bump into you or accidentally trip you or do something, anything to give you a quasi-decent reason to beat the living cr*p out of him.
Admittedly, I had one of those a few days ago. This couple decided to get pushy in the grocery store. I was tired, I was grumpy, and to quote Pantera, I was "f*cking hostile". I had to strongly restrain myself from beating them both to death, right then and there. I don't think they truly realized how close they came that day.
We don't delete posts, for a simple reason - the big boss said so. He can ban me and you can't, so he wins. There's more to it, but that's the only reason that matters.
