"What goes around comes around"

At times people do certain things or behave with others in ways where they actually exploit the other person. And just because the other person is lower to them they feel a power over them where they can get things done and things matlab ANY DAMN THING.
Such breed is found everywhere be it our relatives, friends, colleagues,  wide spread they are.
And when the same treatment is passed onto them they are appalled and sad. But still never ask themselves what they have done to be treated like this and possibly will never ever.
People call themselves religious and adorn various charms and follow rituals yet forget the simple Theory of Karma -
The faces are different and the exploited never knows who is taking his/her revenge and how. But what goes around comes around too and hits you hard at your weakest
