When Jeanne Lyman became a fourth-grade teacher at Holy Family Catholic School in Austin 18 years ago, a freckled, pigtailed Lizzie Laster was in her class. She was a good student, respectful, polite and always smiling. While quiet in the classroom, Lizzie showed a boisterous side outdoors. Neither student nor teacher could have imagined that one day they would be back in fourth grade teaching together in the same school.
