Quote by Iyanla Vanzant: Life will let you get away with something for a while, but sooner or later, you will pay the price. Everything you do in life causes the effects that you experience. When you get the bill, be prepared to pay.
Someone experiencing what they put you through and have their life changed the way their actions changed yours is the best form of Karma. It doesn't matter how long it has been since you did what you Karma will still get you.
