Every one has this switch.. the only difference is that some of us know how to use it and some don't .. The people who don't know how to use this switch can be made mad at will by anyone or they don't know them selves that why they get mad.. So they don't have any control of what they do when they are mad..
For some this switch is automatically turned off when a irritating or a angry person come is close proximity. Is it right for us to get mad when someone around is .. I think that is a high time we shouldn't be. Don't let being mad be contagious thing.. and it stops at you. You will see the mad person will loose their balance when they see that you are not getting mad :-)
There will be people around you who will tell you they have done mistakes and the things when they were mad that they would have not done if they were is the right mind..
So in some ways we need to be mad before we do some of the wrong things. Why we want to do that?
DO YOU WANT TO BE A PERSON WHO DOES NOT KNOW HOW TO USE THE "NOT MAD" SWITCH ???
