Being old seems to be a great excuse
making people believe you feel really, really sorry and miserable about the misery and great harm you caused people.
It is a trick not only war criminals use to not end their life in prison.
Many elderly people use the same excuse.
Parents who never took care of their children, harmed and abused them, seem to think, since time passed by, it is a good reason to forgive and forget, simply because they grew old.
Abusing age to get what you want
is not the way it should be. Respect should be deserved and can not be forced upon someone his throat!
It takes time to forget.
If it comes to time: the soul does not know what time is, so it will take it's time! The only thing one can do is... wait.
Might be you have no time to do so, because you are old or you will die soon, but... you knew you would grow old. Did not you? It is what most people do. Getting old is no reason to force people to forgive you.
If you did harm people
it is something you have to live with! Might be you get away with it, but better count with it, that sooner or later, you have to pay that bill.
