The monthly reading series, “How I Learned,” is back at Happy Ending tomorrow night with stories about drugs. Featured guests presenting their drug-addled adventures include Tony O’Neill (Sick City; Down and Out on Murder Mile), Royal Young (Fame Shark; Interview), Jeff Simmermon (This American Life; The Moth GrandSLAM) and Edith Zimmerman (The Awl; New York Magazine’s Vulture). Host Blaise Allysen Kearsley writes, “It’ll be just like that ’80s TV movie Not My Kid starring Stockard Channing as the mom and somebody as the kid.
