 I was in this one neighborhood where there were quite a lot of them. They're right in your face. And I never felt particularly moved to help any of them until this one guy passed me, said, somebody help me, please. And I turned to see who it was, and it was a man with a white cane, which means he's blind. And I thought, wow, he's worse off than any of these other ones right here. And it struck really close to home because my son uses a white cane.
