Gossip is common. Because it costs nothing. You just have to release it from your mouth, throw in the air, and then it will float in the air. Many will soon come to know about it then. Is there a better way to harm your enemy than gossip? To gossip about an enemy maybe for some fair, because you don't care.
But sometimes we gossip about our friends and close ones. We sit with some of our friends and gossip about others. The one who is used to this habit of gossiping about others will not spare you too. You will soon be part of his gossip to others. It's his habit.
The one who gossips to you will gossip about you!
