That's exactly why you can't hang with idiots, they fukk up everything.
I learned in my younger years the people who don't take serious things, serious, are people who will fukk your life up, and a lot of times its not intentional. Its not just violence, look at sex, people KNOW one nut can fukk up your life if you aren't ready to have kids, but they still fukk with no protection, and there are TONS of birth control out there. Then there are those who have abortions, then cry later on about their decision, but they never seem to think about using protection before that even happened.
Emotional intelligence is lacking in A LOT of people! You could be Einstien, and be dumb as hell when it comes to making decisions that will make your life better or worse.
