(i will use an example cause this is not me xD and i hope this helps you)
An object that I feel that symbolizes a time when I was younger, will be a parrot. I think a parrot symbolizes me when I was younger is because I used to always repeat almost everything that people say. Even if someone I didn't know says something, I would repeat it and I would get in trouble. Another reason why I think parrots symbolized my younger self is because I really liked bright colors all around me. My room was colorful, my drawings were colorful, and my clothes were colorful, just like parrot's feathers, they are different and colorful. One last reason is because just how parrots live and like the tropical weather, I would always want to go somewhere tropical and hot, for an example, Florida. These are my reasons why I think a parrot symbolized my younger self.
So you sound smart and it flows well
1. Beatrice says that the purpose of the simplicity in her town's design is to help them forget themselves. The Abnegation have dull hairstyles and wear dull clothes, and they only eat dull food. They try to keep everything dull because they believe that forgetting yourself makes it easier to be selfless, as vanity causes selfishness.
2. When Beatrice is talking to Caleb, she hears the whistle of a dauntless train in the distance,and says that "it sounds like the Dauntless, calling me to them." She realizes that she wants to be free, and that she doesn't want to give up the part of herself that makes her Beatrice Prior. From this you can infer that she will most likely transfer to Dauntless at the choosing ceremony.
