The more I know about something the less I'm willing to tollerate your shit if you want to argue about it.
I work in an industry that undoubtably touches all of your lives and sometimes people ask "Why?" Questions about it, and I'd offer an explanation based on 15 years of industry experience and then people would argue thats not how it works, or rant at me like I'm the CEO of an entire global industry and generally annoy me to the point where I'm not even going to tell you what industry because I dont want to argue with another single chucklefuck who has a problem with how they do it for you.
