C. Roemmele's letter to Petunia and Vernon Dursley

"On the other hand, he'd gotten into terrible trouble for being found on the roof of the school kitchens. Dudley's gang had been chasing him as usual when, as much to Harry's surprise as anyone else's, there he was sitting on the chimney. The Dursleys had received a very angry letter from Harry's headmistress telling them Harry had been climbing school buildings. But all he'd tried to do (as he shouted at Uncle Vernon through the locked door of his cupboard) was jump behind the big trash cans outside the kitchen doors."
