“For Heidi With Blue Hair” was written by Fleur Adcock, a poet from New Zealand based in Britain. First published in 1986, the poem focuses on a conflict between Heidi, a British schoolgirl, and the repressive authority figures at her school. When Heidi comes to a school with a black and blue mohawk, the headmistress sends her home. In doing so, the headmistress reveals that her authority is arbitrary, capricious, and cruel. After all, the speaker suggests that Heidi’s mohawk isn’t intended to be rebellious or disobedient; instead, it’s a way of grieving her dead mother. The speaker thus endorses rebellion against—and satire of—the headmistress and her power.
