Answer:
"Fame" can also be seen as a metaphor for other aspects of life.
Explanation:
In this poem, Dickinson is stating that fame is sweet to have in its own way, but it also has negative aspects. She mentions a single "wing". This could mean several different things. It could mean that with only one wing, "fame" is only able to fly some before falling or spiraling down and disappearing.
"Fame" can also be seen as a metaphor for other aspects of life. It could be Jesus, for example. The people sung for Jesus, but he then died on the cross for their sins. With the wing, he resurrected.
