Hmmmm..... Forgiveness is key to unlocking one's happiness and peace really and I believe it's a choice. To choose to forgive someone is often a difficult task except with the help of God because left to our natural human logic, people don't deserve it,but how much of the life that we live, do we deserve?
I'm touched already by having to hear someone forgive people even more than a hundred times. There is nothing as doing too much with forgiveness because when yo think that what someone has done to you is beyond forgiveness, you hear someone who has forgiven multiple times and the best you can do is to join the queue of those who make such choice to stay happy rather than live in the bitterness of all that people have done to them.
There are levels of suffering and depths of life that you would have reached that many things become forgiveable/ See the world doesn't know these things but many have done time and paid for their crimes in suffering
