Sonnet 35: 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,
Authorizing 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 my self a lawful plea commence.
Such civil war is in my love and hate
    That I an accessary needs must be
    To that sweet thief which sourly robs from me.
