Two days after the bombings at the Boston Marathon, Boston University students Taylor Mortell and Luca De Gaetano were seated in painting class, their first since BU had resumed classes. But nobody painted that morning. “We naturally formed a circle and were trying to talk about it,” Mortell says. “Everyone was very shaken up by what had happened. Out of this group discussion, Luca and I had expressed that we wanted to do something to help the community heal.”
