Blind?

Blind people on the subway platform make me nervous. I always worry that they will take a wrong step and fall down onto the tracks. That would mean that the rest of us waiting for the train would have to jump down there and save the blind person. Otherwise we would be rotten, rotten people. I run into blind people in the transit system all the time, so I get to worry a whole bunch. Strangely, the blind don't seem to be nervous at all when navigating the platforms, their white canes swinging confidently from side to side an inch above, and intermittently touching, the ground. Good for them.

Another thing I wonder about (but not really worry about) is: How do blind people find those little signs with reading codes that are mounted on the walls, usually next to elevators or exits, or public bathrooms? You know what I'm talking about? I don't understand. Does any blind person ever use those public-reading-code-signs? I have nothing against these signs, that's not what I'm saying, I'm just wondering.
