Soneto 35

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