Blindness- class read

In class, we just read pages 16-19 and have learned about the inner monologue one of the character has to himself. We learn that he has just been to jail and is afraid to go back, after just stealing a car from a blind man that he's recently helped- he is pressured and is filled with a strange worying feeling. He parks the car and decides to clear his head and later finds himself going blind, just like the man he helped.
