Where It All Goes Down
"Love Sonnet 17" is an incredibly intimate poem, so we imagine an incredibly intimate setting. Perhaps the speaker is actually intertwined with his lover in the way he describes at the end of his poem:
so close that your hand on my chest is mine,
so close that your eyes close on my dreams. (13-14)
In any case, the setting is probably quite quiet and even isolated. This love that the speaker describes is hidden and secret, and so the couple is almost surely not walking down the street together or shouting from the rooftops. More likely, they are in bed together, alone, and becoming one.
