What offends you, lady?

Troilus
What offends you, lady?
Cressida
Sir, mine own company.
Troilus
You cannot shun yourself.
Cressida
Let me go and try.
I have a kind of self resides with you,
But an unkind self that itself will leave
To be another's fool. I would be gone.
Where is my wit? I know not what I speak.
Troilus
Well know they what they speak that speak so wisely.
Cressida
Perchance, my lord, I show more craft than love
And fell so roundly to a large confession
To angle for your thoughts. But you are wise,
Or else you love not; for to be wise and love
Exceeds man's might. That dwells with gods above.
Troilus
O, that I thought it could be in a woman—
As, if it can, I will presume in you—
To feed for aye her lamp and flames of love,
To keep her constancy in plight and youth,
Outliving beauty's outward, with a mind
That doth renew swifter than blood decays!
Or that persuasion could but thus convince me
That my integrity and truth to you
Might be affronted with the match and weight
Of such a winnowed purity in love;
How were I then uplifted! But, alas,
I am as true as truth's simplicity
And simpler than the infancy of truth.
Cressida
In that I'll war with you.
Troilus
O virtuous fight,
When right with right wars who shall be most right!
True swains in love shall in the world to come
Approve their truth by Troilus. When their rhymes,
Full of protest, of oath and big compare,
Wants similes, truth tired with iteration—
“As true as steel, as plantage to the moon,
As sun to day, as turtle to her mate,
As iron to adamant, as Earth to th' center”—
Yet, after all comparisons of truth,
As truth's authentic author to be cited,
“As true as Troilus” shall crown up the verse
And sanctify the numbers.
Cressida
Prophet may you be!
If I be false or swerve a hair from truth,
When time is old and hath forgot itself,
When water drops have worn the stones of Troy
And blind oblivion swallowed cities up,
And mighty states characterless are grated
To dusty nothing, yet let memory,
From false to false, among false maids in love,
Upbraid my falsehood! When they've said “as false
As air, as water, wind or sandy earth,
As fox to lamb, or wolf to heifer's calf,
Pard to the hind, or stepdame to her son,”
Yea, let them say, to stick the heart of falsehood,
“As false as Cressid.”
