Sometimes being blind isnt in a persons eye.  People are blind sided by those around them.  There are blind spots in your car when your drive.

Sometimes people can look right at you and not see you, they are blind too.  People who are in there own little world, are blind. 

I walk alot and people in cars dont look around them when they drive, when they walk, when they are in the stores, they stop without looking to see whose behind, besides  them.  These folks are blind too, to the world around us. 

I am always looking around me.  I am very observant of my surroundings.  I dont like to walk into people, or poles, or trees, or trip over water sprinklers.
