"Hey, buddy. Whatcha doin'?" the Philadelphia train station policeman barks as he comes into focus from the background, pointing at the "free hugs" sign. When you are a free hugger your attention isn't on the background. It's on the faces of people right in front of you. He learned in his first year hugging that you can tell when someone is about to hug you by their eye contact. He is sure this policeman will not hug him.
"I think there are a lot of people who can use a hug . . . and I like to give them," he reports for the 331st time in his 5-year love affair with free hugging.
"Let me tell ya," the cop begins. "We might be called the City of Brotherly Love, but we ain't."
