Throughout this book, you seem to always want to leave Mango Street, to leave your family. In the end you even wish to leave Mango Street behind, with your family and the memories you have there. Nenny, although annoying at times, just wants to be your sister and be just like you. Even though your parents may seem overbearing or stern at times, they are just looking out for you. You need to realize that you will always be part of your family in Mango Street, and everyone in it plays a vital role in your growing up. Your family will always be there for you no matter what happens, unlike the friends that you may have for a while then they go away.
Nenny is an irreplaceable and special person in your life. Not only is she your sister, but she looks to you as a role model, and forces you to show your best.
When you are with Rachel and Lucy, and Nenny is with you, she sticks by you even when they tow of them are making fun of you and your family. The two girls say things like, "Nenny, you better tell your sister she is really crazy because Lucy and me are never coming back here again. Forever"(HMST, pg. 23). Nenny stays with you and just keeps on naming the clouds. Also, when she is jumping rope with you and the two girls, she uses the same rhyme, you seem to get annoyed with her. I remember when I was younger, I used to try and sing along with my sister when she was listening to it. I would mess up the words a lot of the time, and she thought I was trying to bug her, so she'd get mad...
