I don't get it

It seems as though i don't get a lot that goes on. Things always tend to be my fault, even though the other side is perfectly liable to be in the wrong too; I just end up getting yelled at for the whole thing. This is how it usually goes, pretend that i'm standing at an intersection with a bunch of other people waiting to cross the street. It takes forever for the lights to change and for us to be able to walk across, and so i get blamed for not pressing the pedestrian crossing signal when everyone standing there is just as much at fault...but of course I somehow am the one who's to blame. I don't think it's fair when people don't try and see both sides and they automatically say it's your fault. You'd think people are smart enough and care enough to do that favor for you. The world is filled with too many excuses. If you promise you're going to do something and never prove that you did...what good is it? You can't just tell me you fixed my computer, you have to show me you did. A man can't tell his wife that she's more important than his car, and spend every free moment cleaning it or enhancing it. It doesn't work that way...why can't some people understand such a simple idea?
