I have this fuzzy memory of sitting in a classroom, maybe in elementary or middle school, listening to a faceless teacher lecture about Helen Keller. At least, the class was probably about her as I don’t remember public school teaching me much about anyone else from the history of the blind. When the lesson was over, my classmates and I were invited to participate in an exercise that was supposed to “put us in the shoes” of someone living with a sight-related disability.
