This is the world. Where people are daft enough to argue over whether or not they're going to kill a person. Usually it's not really something worth wasting your breath over. You've got a problem with an old mate down at the bar? Swing by and cut his fucking throat. Don't think about it. If you do that, you're never going to get anywhere. You're just going to make yourself look like a moron by running your mouth. No one cares about what you want to do. If I had a dollar for every time someone told me that they wanted to kill me, I'd be richer than the fucking Queen. Your actions speak louder than your words.
So if you're going to kill someone, just bloody well do it. If not, shut the fuck up and stop flooding the boards with your big talk.
