There's nothing new about this idea. People have been doing it for centuries. But, how many of us actually sit down to eat with our neighbors anymore? What if we had quarterly or monthly dinners inviting students to sit down with their neighbors? Not their families, or direct neighbors - but the larger community? A community-wide "mix it up day."
Social justice and civic engagement doesn't have to start with a conversation about race or gender. It can start with a conversation about the local sports team. When we know and can relate to each other about daily concerns, then we can more easily empathize with those whose concerns are outside our own experience. When we call each other friend, we are no longer us vs. them.
