My experience with hearing loss
I managed to get through grade school by re-reading all work from each day. High School was a different story as it was a Secretarial School, whereas they taught Shorthand/Dictation/Transcription along with other business courses. In New York we could get high paying jobs in business offices. My mother wanted me to be a secretary not a beautician like I wanted to be. My parents/teachers were ignorant of my hearing loss and of course I thought everyone heard/didn't hear as I did.
One of the surest ways I knew something was wrong was when the teacher would dictate sentences and we had to write them in Shorthand, then type them.
