Why do people lie about others?

When friends get into fights with each other one of them usually starts saying lies and spreads rumors. This causes the fight to become worse and the friends now want revenge! So both friends spread lies and get back at each other. Now other people join in and cause more problems. I think that these friends should talk things over with each other in a calm way instead of saying bad things about each other. They probably got into a fight over something that could've talked over and made better. Now they have to deal with the lies they told and the people that got involved. They spread these lies over anger and that's not a good. Just because you're mad and hurt with someone doesn't mean that you have the right to say things that aren't true about someone.

I think people also lie because of jealousy,envy, anger, and sometimes just because they like making people feel and look horrible just to cover up the person they really are. Nobody should lie about anyone; if they do sooner or later the truth does come out about the lies and the liars so the best thing to do is not to not lie at all. No one will want to be your friend and no one will want to ever trust you.
