We talked to a man named John whom I ended up buying a lunch of jambalaya. He was a man looking for a meal. Testing this proposition, I offered to take him to lunch instead of accede to his demand of $2.
I learned that he was a repairman who as a result of Katrina, had become temporarily paralyzed. He'd lived in New Orleans for a long time.
Apparently, he was able to shake off his paralyzation, contrary to what the doctors' had diagnosed for him.
He was now walking, and was simply happy to do that. However, he was unable to resume his day job and we found him begging at the French Quarter for change.
