Here is some food for thought. Uncertain what street I am on, I will stop and ask someone. This is categorized as asking for help. Uncertain about what street they are on, a sighted person looks up and reads the street sign. We do not call this help.

A street sign does not magically appear suspended above our heads. It was ordered, made and hung there to aid people navigationally. However, if you can read it with your eyes, the effort behind and purpose for the sign’s presence is stripped away. You are functioning independently by reading information that is just there.

Why?
