Sonnet XXXV: No more be grieved at that which thou hast done

No more be grieved at that which thou hast done:
Roses have thorns, and silver fountains mud,
Clouds and eclipses stain both moon and sun,
And loathsome canker lives in sweetest bud.
All men make faults, and even I in this,
Authórizing thy trespass with compare,
Myself corrupting salving thy amiss,
Excusing thy sins more than thy sins are:
For to thy sensual fault I bring in sense—
Thy adverse party is thy advocate—
And ‘gainst myself a lawful plea commence.
Such civil war is in my love and hate,
 That I an áccessory needs must be
 To that sweet thief which sourly robs from me.
