Mrs. Graziano

Mrs. Graziano, who is the school's music teacher, only appears in the Diary of a Wimpy Kid: Old School

She goes to Hardscrabble Farms on the schools field trip, and states that she has been going on the trip for many years. She appeared to be the head of the field trip since she told the kids the rules, and had the chaperons to search kids bags. Greg and his cabin-mates accidentally swipe her bag when they raid the girls' cabin.
