The mother of Gerry Ridgeway [letters, Jan. 15] did teach him correctly on how to cross a street: You do look both ways. That is, unless you are blind.

Having volunteered with organizations for the blind, I know that the blind decide when it is safe to cross a street by listening. Even people who have guide dogs listen and then give their dogs the command to proceed. Silent cars are dangerous to the blind.
