Line copying

Line copying is a punishment mostly considered to use by Muggles. In the 1991–1992 school year when Rubeus Hagrid led Draco Malfoy, Neville Longbottom, Harry Potter and Hermione Granger into the Forbidden Forest to find a hurt unicorn as detention for being out of their beds after bedtime Draco complained that this was servant's stuff and that he thought they'd be copying lines. Hagrid answered that this would do nothing good for anyone.
