People wear shirts that promote many things, from their favorite sports team to a picture and quote from a funny movie. But clothing can also promote ideas. And ideas can be powerful. Peace is an idea. The idea that we all can live together with love, and not violence. Life is an idea too. Yes, it is a physical trait, but it’s also an idea in the sense of what is life and what does it mean. Peace and life, when put together, can change the world. And that’s a pretty special thing. Symbols help represent ideas.
