I thought the story line was great.  He described a lot about who he was and where he came from.  With that to set up the story, we got the idea of why people would lock their doors when he walked by, or acted like he was a person who would steal, or mug someone in the park.  I believe that this has been happening for a long time.  I think it is still happening to this day as well.  The people that act really perinoied are the ones that freak out when something doesnt look right to them.  You just got to look for the first sign  they would make to judge what they might do to you.  If most people would relax when they encounter this, we would all be better off.
