I met Michael in a Boston subway station. I told him I liked his sign. “What matters is what it means to you,” he told me. I asked what it meant to him. “Doing a deed or expressing kindness to another person without expecting anything in return,” Michael said. I love approaching strangers wherever I go. Listening and talking to them teaches you about people and how similar we all are to one another. Just like Michael, we’re all seeking human kindness.
