"Celebration"

Celebration means joy, laughter, happiness and fun. We attempt to celebrate events', birthdays', graduations' and weddings'. But, how can we celebrate festivities when we fear being among each other?  There are guns instead of horns. There's arguing instead of music. There's vulgar language instead of jokes. There are tears instead of laughter and evil eyes piercing at another through the crowd. And this is the way "Humans" celebrate???
