Through out the book of Little Woman, Amy may be the smallest and not included as much as the others, still happens to make the biggest impact which is proven below. With such an odd personality makes the book different than without her.
With Amy, the thing that stands out is she just about shuts down her brain sometimes. Like when she burnt Jo's books in the fire when Meg and Jo didn't take her to the theater. Plus you can about tell that she over reacts and shows immaturity about the example I gave you. Plus with being the youngest comes with some perks. Like Marmee trying to get Jo calmed down so that she would not be frustrated with Amy. I think if it was Meg or Beth who burned the stories, her mom,Marmee would have probably let Jo keep going at Meg or Beth.
Enough with bad things about Amy, lets get to good things and her personalty. She was kind of nice when she gave her Christmas breakfast to the people in need. She also purchased a bottle of perfume for her mom, Marmee, with her only dollar. From what I can see from the book Amy is a great drawer. Drawing is shown in the book to be one of her true hobbies. It shows when she copied paintings in the Laurence house. She also likes to look at art to get inspired or get an idea.
With such unique character traits it is no wonder why Amy, a 12 year old girl, can make such an impact on a story.
