Why don't we complaint?

In today’s society there a lot of people that doesn’t complaint maybe is because they doesn’t want to create a bigger problem. But, why you don't complain if you know that you have the right to complain? I know, maybe is because you are shy or you fear that the problem is going to get worst. People doesn't understand that we have the liberty to express our feelings and thought at anytime without fear of punishment. You are not to gain anything if you stay quiet and don’t fight for your rights. The author did a mistake by staying quiet. Your voice needs to be heard when there are other that are doing the wrong thing. In my own opinion, I think that we all should complain when you feel that you have to, nobody is going to do it for you.
