Why people screw other people over...

I was having a conversation with a friend one day, and she asked me why I think people get screwed over and here is the response I came up with...

It's almost second nature to just screw someone over...matter of fact, that's human nature...no matter how close you may be with someone, if there is something out there that is better for you and can't include the other person, you will pick the one that's better for you. Now obviously there are certain extremes to that statement but it does hold some truth and the thing is...

we've all done it at one point or another

BUT some people care and some others don’t...while I care that I've done it before and hurt someone and don't want do it again and try my best to avoid making that same mistake twice...there are MANY who just don't give a crap and would rather look out for "numero uno" - and that is just part of Human Nature
