I felt, that in our life a time comes when it feels that we had done a lot many things which should not have done and it can't be changed now...but yes it gives you the precious eye opening moment which is not to regret upon, but its better that understand what to do at what time with whom so as not to come in the same position again....So just spread love and happiness because it hurts that you could have done it but now you have nothing in your hand.
