What are the qualities both common to Maddie and Peggy

Maddie and Peggy both sat at the front in class with students who scored good marks. There is a bit of teasing streak in both. They often waited together for Wanda to have fun with her. However, they are not cruel by nature. They treat this practice of teasing Wanda as a game. Peggy, in fact protected small children from bullies but could not realise that she herself was being a bully. Maddie often wondered at the futility of asking the same question from Wanda everyday. But, they continued because it was great fun for them to do so.
