Shakespeare's Sonnets: Say that thou didst forsake me for some fault

Say that thou didst forsake me for some fault,And I will comment upon that offence,Speak of my lameness, and I straight will halt,Against thy reasons making no defence.Thou canst not (love) disgrace me half so ill,To set a form upon desired change,As I'll my self disgrace, knowing thy will.I will acquaintance strangle and look strange:Be absent from thy walks and in my tongueThy sweet belovèd name no more shall dwellLest I (too much profane) should do it wrongAnd haply of our old acquaintance tell. For thee, against my self I'll vow debate, For I must ne'er love him whom thou dost hate.
