When you get them out of your life (to stop harassing you) there is a lot of weight lifted off your shoulders, just like water off a butterflies wings. :)
No matter what people say, you choose if you want to listen to it and let it destroy your life. You don't have to listen to the rumours or lies told to you.
It means to be free. Life is short so make the most out of it. People can be like Butterflies, can be free but things can hold you down if you let them.
