I've been so inspired by Hoa Nguyen and the writing prompts she's given to our poetry group at the Banff Centre.This prompt comes from an exercise we did yesterday, and from "Question Manifesto" (read below), a poem developed with Hoa Nguyen by a group of poet participants in a seminar program founded to support conversation around aesthetics, resistance, and politics.
