A former gym teacher, Mrs. Weera is tall and athletic, and she insists that she's not afraid of the Taliban because she could outrun the soldiers—and outfight them if necessary. In her youth she was a runner and earned medals for her speed, though she lost most of them in Kabul's many bombings over the last decade.
Mrs. Weera, an older woman, is a friend of Parvana's family. She doesn't let the Taliban's oppressive rule make her sad or despondent, so she throws herself into getting Mother back up. She's part of a secret women's group and takes pride in being able to resist the Taliban in underground, quiet ways. At the end, Mrs. Weeras is prepared to take Homa with her to a refugee camp in Pakistan, where she plans to start a school and work on more resistance efforts with her women's groups.
