I'm Nobody! Who are you?
Are you—Nobody—Too?
Then there's a pair of us?
Don't tell! they'd advertise—you know!
How dreary—to be—Somebody!
Dickinson’s poetry is iconic for its use of “em-dashes” (i.e., —).  If we were to look at the Dickinson archives, we would find that publishers have take some liberties with how the poems are presented on the page, but the em-dashes are still present. 
 One interpretation of her use of em-dashes is that she tries to create a “palpable urgency” for the reader. However, we could also read the dashes as a Dickensonian hermeneutics: she is giving the reader a method for reading the poem, a halting, uncertain, emphatic voice that helps to make her poetry so accessible and delightful.
