Why didn’t Maddie ask Peggie to stop teasing Wanda? What was she afraid of?

Maddie tried to tell Peggy to stop teasing Wanda by writing a note to her. She knew she would never have the courage to speak to Peggy about this matter. As she was writing the note, she pictured herself in the school yard as a new target for Peggy and the girls. She thought Peggy might ask her where she got the dress she had on and she would have to say that it was one of Peggy’s old ones. This was what she was afraid of. Consequently, she ended up tearing the note.
