Peace is in your heart not outside. If you don't know what peace means then don't wear the sign because it makes me mad when people don't know what it means and then that's not very good for me.Peace what is it well its something that we all live together and love one another no matter what they are or how they think but most important its not how they dress.We all should express our self in our own way and say what we think and never think what other people think.If we do that then we will never live with ourselves and if we cant live without ourselves because of what other people think then you will never move forward.If we could just live with one anther then we all shall live in a non war and peace loving beautiful place and everyone will hopefully be happy. love your friend Anna
