They always say this:
"Forgive and forget"
In order to live peacefully

Forgive the sinner
Forget his sins
And yet to me
I shall forgive the sinner
And forget him, too
For I cannot live with peace of mind
When the sinner has been forgiven
Too many times
But still the story repeats-
     Sinning
     Forgiving
     Another sin
     Another forgiveness
How shall I forget then?

It is still best to let go
Of everything about the person
Who sinned against you
So you can live peacefully.
