And for 15 minutes, people just stared right through me. The first person who stopped, tapped me on the shoulder and told me how her dog had just died that morning. How that morning had been the one year anniversary of her only daughter dying in a car accident. How what she needed now, when she felt most alone in the world, was a hug. I got down on one knee, we put our arms around each other and when we parted, she was smiling.
