I know

I know,
There is no sadder moment,
Than losing a parent,
I know,
There is no happier moment,
Than having fun with a parent,
And I am sorry for every mistake I did
When I was a kid.
I forgive every mistake you had done
And your mistake which scared me,
By holding a gun.
This I give it to your grave.
May God bless you
For the caring you did,
In my whole life...
