Poison,

A man went to his father and said: 
‘Father, I can't take it anymore, my wife is driving me insane!!! I want to kill her, but I'm afraid someone might find out I did it. Please help me?!
The Father replied:
‘Yes I can help you, but there's a but... you're going to have to make amends with her so no one would suspect that it was you, when she dies… You'll have to take very good care of her, be kind, grateful, patient, caring, less selfish, listen more and help her with chores... you see this powder here? Every day you have to put a little in her food. So, she dies slowly.
Thirty days had passed and the son came back and said to his father:
‘I don't want her to die! I have come to love her. And now… how do I cut the effect of the poison?’
Then the father said:
‘Don't worry! What I gave you was rice powder. She's not going to die, because the poison was in you!’
‘When we feed grudges, our love slowly dies. When we make peace with ourselves and with those who offended us, then we can deal with the other, as we would like to be treated.’
Then, we will have the initiative to love, to give, to offer, to serve, to care for... and not just have the need to win, to be served, or to take advantage of and exploit the other.
We all need to stop, pray and ask for that antidote called forgiveness.
