how is the theme of loss and separation explored in remember, a mother in a refugee camp and poem at thirty nine?

The three poems Remember written by Christina Rossetti, A Mother In A Refugee Camp by Chinua Achebe and Poem at Thirty-Nine by Alice Walker share the same theme of loss and separation. Remember explores the pain of losing loved ones. A Mother In A Refugee Camp emphasizes the relationship between a mother and her child living in a refugee camp. Poem at thirty nine is a poem about the reminiscences of a loved one. Remember expresses the pain in losing and letting go of a loved one. This is shown through the techniques of imperatives and contrasts. The first few words said by the speaker are "remember me". This is very effective in expressing the personas demanding tone. This quote can have multiple interpretations such as speaking in a selfish tone or a concerned tone. The usage of ‘remember’ , shows that there is a sense of fear the speaker holds that their lover might forget them too quickly. The title itself consists of this word which shows the power of the word and the entire poem. The speaker at first appeals to her lover to remember her after death, but as the poem progresses she dispels her selfishness. As the poem unfolds the reader understands that there is separation between two lovers. The reason of the separation becomes clearer when "gone far away" is used. This quote conveys the concept of death. The speakers sorrow is stressed by the reappearance of the words 'gone away'. All sonnets are known to have a change in tone within them; this sonnet has a change in tone from negative to positive. In the two quatrains the speaker’s focus shifts from ‘remember’, to the word ‘forget’ towards the end. This supports the change in tone; she changes her tone from talking only about herself to thinking about the other person. Sonnet 116
