This waiting shows the altered state of mind that the narrator is placed in due to the strong emotion of love that he feels for the lover. The narrator refers to his time as not being precious unless he is serving the lover, and serving the lover adds intrinsic value to his time. In all of this dealing with time and references to it, the narrator is trying to convey the message that love has much to do with time. Over time love can grow stronger, weaker, more or less troubled or any variety of ways. In sonnet 57, love is addressed from an ontological perspective.
Love is personified and treated as if it had a life of it s own.
In sonnet 57, love as a theme is directly addressed, but in sonnet 58, love is only referenced through the description of the slavery in which the narrator is placed. The narrator in this case is giving up part of his self determination and allowing the lover to be dominant over the narrator again. The narrator opens himself up to the judgements and controlling nature of the lover repeatedly throughout both of the sonnets. Shakespeare uses many different methods of discourse to examine this theme of love. In both sonnets the lover is exerting his control over the narrator, but the narrator does not really mind being controlled in either sonnet.
