(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.
