What is the theme of sonnet 9?
The theme of Shakespeare's sonnet 9 is impatient love. The first two lines ask a question: " Is it for fear to wet a widow's eye,
That thou consum'st thy self in single life?"
The narrator is asking the object of his love if she's afraid of being a widow, and that's why she hasn't had married/had children yet. The rest of the sonnet puts pressure on her to do so, with the strong implication being that she should do so (should have kids with, and therefore make love with) the speaker. The poem ends by proclaiming such a decision to be a selfish, shameful act.
