Based on the details in the excerpt what is it primary purpose

I don't believe that people, even those that she called her family, really truly knew her and understood her. In fact, they mostly just took her at face value, believing her to be happy and joyful all the time rather than having her own internal issues. Jane and the children view Aunt Imogen mostly from a standpoint of the cheerful type that always is around to make others happy. However, they fail to look deeper and make a deeper analysis of who Aunt Imogen really is. In order to really know someone, it's important that you look further than just face value and how they appear on the inside, and to truly know yourself is more or less the same thing. You have to be familiar with your emotions and how your mind works in order to really truly know who you are as a person. As expressed later in the poem, Aunt Imogen has sadness and feelings of loss and loneliness deep inside of her that she doesn't show to much of anyone, if she happens to show it at all.
