I shall but love thee bitter after death

An injured friend is the bitterest of foes.

Kindly permit me to tell you, sir, that I hate you. I hate you and your child, as I hate the life of which you are the representative: cheap, ridiculous, but yet triumphant life, the everlasting antipodes and deadly enemy of beauty. I cannot say I despise you - for I am honest. You are stronger than I. I have no armour for the struggle between us, I have only the Word, avenging weapon of the weak. Today I have availed myself of this weapon. This letter is nothing but an act of revenge - you see how honourable I am - and if any word of mine is sharp and bright and beautiful enough to strike home, to make you feel the presence of a power you do not know, to shake even a minute your robust equilibrium, I shall rejoice indeed. -

Stronger than alcohol, vaster than poetry,
Ferment the freckled red bitterness of love!

there is, after all, no harsher bitterness than that of a person who is his own worst enemy.

Batter my heart, three-person'd God ; for you
As yet but knock ; breathe, shine, and seek to mend ;
That I may rise, and stand, o'erthrow me, and bend
Your force, to break, blow, burn, and make me new.
I, like an usurp'd town, to another due,
Labour to admit you, but O, to no end.
Reason, your viceroy in me, me should defend,
But is captived, and proves weak or untrue.
Yet dearly I love you, and would be loved fain,
But am betroth'd unto your enemy ;
Divorce me, untie, or break that knot again,
Take me to you, imprison me, for I,
Except you enthrall me, never shall be free,
Nor ever chaste, except you ravish me.

...to the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee.

I scorn your idea of love,' I could not help saying, as I rose up and stood before him, leaning my back against the rock. 'I scorn the counterfeit sentiment you offer: yes, St. John, and I scorn you when you offer it.

Rest you, my enemy,
Slain without fault,
Life smacks but tastelessly
Lacking your salt!
Stuck in a bog whence naught
May catapult me,
Come from the grave, long-sought,
Come and insult me!

Thus with my lips have I denounced you, while my heart, bleeding within me, called you tender names.

It was love lashed by its own self that spoke. It was pride half slain that fluttered in the dust. It was my hunger for your love that raged from the housetop, while my own love, kneeling in silence, prayed your forgiveness.

A town loved with bitter love.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

If you write something that you love beyond all reason, it is wrong and you should strike it out.

He who made you bitter made you wise.
