Nothing is forgotten but one can sincerely forgive.
I think forgetting comes after forgiveness.
Not for humans. We can forgive but no human really forgets.
If you trully forgive, you can't forget! Not the way I think you mean it... So don't forgive, just forget, and the forgiveness will come. ;)
For me forgiving comes after a very long time and its very rare but I never forget ever.
It is .. but often it just take some time for it to happen.
A well placed knock to the head with a rock will solve both those problems.
That's what I've found...
