Ever wondered how a world without words would be? Would it be better, or worse? Would the silence be unbearable or a relief?
Words can bring happiness, but they can hurt in so many ways. A word is often enough to ruin a friendship, to break a relationship, to cause a war or to bring an end to an ideology. Because they are so powerful, it's very easy to misuse them - isn't it fun to say all those words during an argue? Even if you didn't mean them, they leave permanent stains.
Hence, maybe a world without words is a better place. Maybe we employ them just because we're too coward to do the things that we want to; maybe we speak them because we're just afraid to let others know what we feel.
