The speaker in the poem "Miss Rosie" is unspecified; therefore, it could be any number of possible people such as a friend or a family member or a scorned lover. It could also be an internal dialogue in which Miss Rosie is actually speaking to herself. What is clear is how strongly the speaker feels about Miss Rosie using such vitriol. The poem explores the effect of disappointment on relationships, and the language that the author uses is quite strong and harsh. It unfolds like a chastisement for a wasted life, and denigrates her severely.
