A letter that ends with its better late than never

 Dear, Anna

            You've moved away but your still my best friend.  A lot has happened since you left. My big brother Joey finally went to collage, and Mom got a good paying job. I'm doing OK in school, or so my mom says. We miss you, but good thing you left because Lily, our bully, just moved in across the street.  I have to go do my late homework, it's better late than never>

                                                    Love, Lou

Explanation:

hello,

your answer is a) the metaphor suggests that the poetic themes are serious and dark.

collins is comparing the poem to a dark room. he is suggesting that the poems theme is serious and wants you to understand it. you don't need to understand the poet in order to understand the poem. you also don't need to move around while reading it. he is simply saying the poem has a dark and serious theme.
