David A. Thomas, president of Morehouse College (GA), writes:  For two days, I turned back the clock and lived like a freshman at Graves House, the oldest dorm on the campus of Morehouse College. It was a social experiment that allowed me to bond with a group of young men from across the world who were experiencing their first taste of independence. I packed lightly, toting only a duffel bag and a bottle of water, so they wouldn’t think that “big brother” had arrived to snoop. The responsibility that I carried with me as president of the world’s only historically black college for men was already weighty enough, particularly on that day, with the arrival of 730 new students.
