Castles and crappy parents

The trailer is out for the upcoming film adaptation of Jeannette Walls’s memoir The Glass Castle. I tend to get this book confused with I Capture the Castle (another story about poverty and sub-par parenting), and I doubt this movie will do much to keep the stories separate in my mind. Both books leave me profoundly grateful I didn't spend my childhood being subject to the whims of a pair of pathologically self-involved parents, though. Thanks, Mom and Dad!
