Yes, we all do! why do we deny it? Denial prevents us from learning and growing. In any situation, no way that the fault rests on one side only. Each person bears some responsibility to what had happen. The true stupidity is to do the same mistake over and over with out learning the lesson to do better each time. I am surprised that some people wrong others for no reason but envy then they demand forgiveness as if it is a right for them. Surprisingly, when they try to fix up what wrong they inflected on others, they do it wrong as well. I believe the the real change comes from within. Faking being nice won't work! People will find out or at least will feel it. Let's be truly nice to one another. Life becomes more fulfilling and enjoying! When we see good in others' life, let's be happy for them! Envy is a negative energy that destroy the one who is ailed by envy and it will certainly damage the relationship. Let's free our heart from envying one another and instead let's fill it up with the desire to see others growing and living their lives happily. Even, let's contribute in making others happy. By doing so, we will be happier! Wish you all very happy life in this life and in the hereafter.
