How is Wanda seen as different by the other girls? How do they treat her?

Wanda was different from other girls. She did not have any friends. She came to school alone and went home alone. She always wore a faded blue dress that did not fit her properly. Unlike others, she did not talk to anybody. The other girls teased her and had fun with her. They would surround her, and Peggy would ask how many dresses she had. Wanda would reply that she had a hundred and they would continue teasing her. Then, they would let her go. Before she could go very far, they would burst into laughter. They kept asking her how many hats she had, or shoes, etc. All of them mocked her and made fun of her.
