From the same title we can see the meaning or theme of the poem, @johnjgeddes. There is a being that misses another. The other person, absent, has become part of his routine. The subject in love smells it, feels it walking in his thoughts, glimpses it between the lines of his text, remembers it still on the walls. Time is a marker of the hours of absence and solitude! It is not only longing for the other person, waiting for him, but not knowing if he will come back! Happy night, poet.
In this poem, Nancy, rain and storms are familiar metaphors I use to connote separation and conflict - usually unfulfilled longing, and of course, the gears of the clock are relentless, always grinding away the time until nothing remains but emptiness. Storms always separate us from those we love
