spinning around and around

everyone must realize that if they do something to a certain person if it good or bad,they will receive the exact same thing like what they do. have you feel like that before? i'm certainly never have felt it (hope that it will never happen to me) but i almost have hear it from my friends and at the end they always regret about it. so what i mean is don't do something that make hurt anyone if you don't want feel the same and try to do good thing to anyone if you want your life full of enjoyment because your good deeds will be replied by anyone whom you did it to
