Sheryl Sandberg gave a powerful commencement speech but there’s no way to prepare yourself for heart-wrenching grief

Sheryl Sandberg’s weekend commencement speech was a beautiful and moving testimony about grief and resilience. After the tragic death of her husband Dave, she took to Facebook to reflect on her loss. This weekend, she took to the stage to tell Berkeley’s class of 2016—and all of us—about her own sorrow in the hope that we might learn from it.
