Something which I was reading about gossip.
From the mentality of the gossiper its a funny moment for him to spread things and fool around. But in actuality a gossiper does this because either he doesn't have the guts to speak things in front of the person of whome he is gossiping about.
Every gossiper is always afraid of confronting these thoughts with a person he gossips about. Thus he finds a medium to gossip around in public and find a funny moment out of it.
