First I was thinking that complaining or criticizing some one is bad manner. Another person will hurt or feel bad about it. But I was wrong. One of my friend has bad speaking manner. He has a rough language as though he is insulting you. When I told him he looked at me and think for a moment. When he met me after two days he says I am right, he speak with his friends. now on he will change his habit. So, If you see something wrong going around you or your friends, speak up, crticise about it and draw attention of that person or persons about this wrong thng or weakness. May be that person rethink and revised himself. May be he will thank you for this.

So, Speak Up, complain, criticize the wrong things around you
