Defaming you without provocation

I´d just stay away from them.

It is better to leave it to Supreme power because even if u wanna avoid them and severe all contacts from them, there is always a person who knowingly or unknowingly becomes a middleman. Such middleman person more or less are non other than your very close friend or relatives u trust the most. They will always lecture u not to get harsh, always say we aren't your enemies and will want you to forgive that person who is defaming u. Best solution is to show them directly or indirectly that u r not liking their behaviour and let them know that u r aware of their intentions. The supreme power will take care of the rest!

well I call it life and it happens with or without us doing anything.

I believe what goes around comes around. Its good to confront the person if you have enough evidence.. but often times there is not much evidence.

I agree that there are such people in the habit of gossiping and lobbying against you behind you. I think that it is related to their personality developed at an early age. I usually ignore this kind of people pretending nothing has happened, but I will be more careful when I know such a person.

Some people are so unhappy that they can not survive unless they make others miserable. I wait for the supreme power to set things right.
