Hamlet

Father references stuck in my mind when you mentioned this. This is a scene from Hamlet, Hamlet is grieving because he’s lost his father, his uncle is going to marry his mother. This is Hamlet’s uncle now step-father speaking and Hamlet thinks the uncle has done away with father to steal the throne.

'Tis sweet and commendable in your nature, Hamlet,
To give these mourning duties to your father;
But, you must know, your father lost a father;
That father lost, lost his; and the survivor bound, 90
In filial obligation, for some term
To do obsequious sorrow: but to persevere
In obstinate condolement is a course
Of impious stubbornness; 'tis unmanly grief;
It shows a will most incorrect to heaven, 95
A heart unfortified, a mind impatient;
An understanding simple and unschool'd;
For what we know must be, and is as common
As any the most vulgar thing to sense,
Why should we, in our peevish opposition, 100
Take it to heart? Fie! 'tis a fault to heaven,
A fault against the dead, a fault to nature,
To reason most absurd; whose common theme
Is death of fathers, and who still hath cried,
From the first corse till he that died to-day, 105
'This must be so.'
