Sonnet One Hundred and Twenty-nine is more of a rant than anything else. Throughout the piece, Shakespeare's thoughts keep changing, evident in the use of altered tenses, such as the utilization of had, having, and have within one sentence. The reader cannot deny that the previous sonnets have all included varying sentence count and structure, making it very strange that this sonnet contains only two sentences for all of the lines used. The notion that the first sentence is just an extremely continuous sentence is just further proof that Shakespeare has a lot to say about passion.
This is the first dark lady sonnet that we explored within the classroom. I find it interesting that Shakespeare alternates between negative, positive, and negative feelings about his (or the speaker's, for we cannot assume the speaker is definitely Shakespeare) passion for the subject (who also could potentially be someone different than the dark lady.) Perhaps this is meant to show how passion toys with an individual's mind, clouding thoughts and emotions.
