On a cold night this past February, our guest shed his business suit, put on the most beat-up clothes he could find, and hit the streets for a night of homelessness.  Dr. Matthew Shank is the President of Marymount University, and the idea of doing this occurred to him after receiving an invitation to speak at an A-SPAN fundraiser.  A-SPAN is a local nonprofit dedicated to ending homelessness in Arlington, and after accepting the invitation Dr. Shank realized he didn't know a thing about being homeless.  He also felt compelled to heed Pope Francis' call to stay close to the marginalized and to be shepherds living with the smell of the sheep.
