I have to analyze a poem for English class with no certain prompt given. I am basically told to write about the poem and how it appeals to me, and what the poet uses to make the poem, etc.

I need to know why did Pablo Neruda choose to write about socks, and how can I analyze the poem to make a 4 paragraph essay?

I am extremely stressed and frustrated since I have no direct prompt..
Any suggestions will truly help so please help me out. Thanks!!

(I also can't put the poem on here because it's on the only book and it won't let me copy it)
