'Parting at Morning' is the companion poem to 'Meeting at Night' which details a lovers' tryst. 'Parting at Morning' is about the two lovers going their separate ways the next day. There has been debate about who the narrator of the poem is but Browning suggested that it is the male lover speaking.
The poem suggests the fleeting nature of love which makes the parting of the lovers inevitable as he has to return to 'the world of men.' Love is like the night itself; over quickly to be replaced by the perhaps harsher reality of the day.
