On a cold Saturday morning in a dance studio under the Hawthorne Bridge, a group of a dozen or so amateur actors gathered for the first of a two-day Theater of the Oppressed workshop hosted by Living Stages Theatre, a nonprofit, social action-focused theater. Participants gathered with a common mission: To create a piece of theater addressing their own experiences with homelessness and “root shock” for Living Stages’ upcoming Forum Theater Convergence, a festival featuring pieces of theater in which audiences are invited to intervene in the actions presented on stage.
