sentences:  The relationship is expressed throughout the sonnet with the use of words like "torture", "slave", "torment", "prison", and "jail".Critic Stephen Booth holds that the metaphor within this sonnet is "so complete, so urgent, so detailed… that the lovers and their situation, and their behavior becomes grotesque".Booth proceeds to note that, although the slave imagery is a commonly used metaphor, the wording of the speaker's metaphors creates a witty and unconventional depiction of his relationship with the unknown woman.
