Then I am right you are a jerk...
Always ask permission first before mouthing off at people. You might be one of those people that think they are right also. ALWAYS ask, don't just tell people what to do. I 100% bet if you use those words I said you will never get a FU. You just come off very rude to people intervening on others. You aren't their boss, you are not their parent. You have no authority over them so don't act like you do. In the end of the day you are all playing a game.
