Maia Piermattei, 20, a university student, was among thousands packed into George Square listening to Thunberg. She said she was struck by how young Thunberg looked. “She’s not just young, she’s physically small, she really looks like a child,” Piermattei said. “And yet what she says is so powerful. She has leadership.” Piermattei contrasted this to the leaders gathered at the COP26 summit, where she has been waitressing. “I don’t feel as represented by them as I do by Greta. She feels like one of us.”
