What judgement did he have about the homeless before he became homeless himself? Working, living in a home of his own, educated....now homeless.
When he passed the homeless guy at the corner, did he stop to give some coins? Did rush on by and pretend not to notice? Did he judge and question "How could they get like that?"
Was he one that cast fear "Don't look at them, they might attack"
Does he remember his thoughts about people on the streets before he became one?
