I was going up to the board to copy the class work off onto my paper, then going back to my desk to work it (and I sat on either the front row or the second row - it's been a few decades since 5th grade). The teacher and principal were members of the same church and Mom taught in the high school (different principal). It got mentioned to the preacher (Dad) and Mom both very quickly.........
My teacher should have caught on much more quickly than she did. I was doing the same thing, going up to the board to memorize what we were supposed to do. Teacher told me to stop. I explained that I couldn't see it, because she was "writing too thin." (Green chalkboard, and the yellow chalk they used just faded right into it.) I told my mother this, and got told not to be silly. They just did not decode what I meant. I asked to be moved to the front of the room, but Teacher wanted all of the class sitting in alphabetical order. So I started deliberately breaking the point on my pencil several times a day, so I could go to the pencil sharpener at the front of the room.
Like most kids with bad eyes, I thought this was the way everyone saw, and I didn't believe the other kids who claimed that they could see it just fine. They lied about a lot of things, so I had no reason to think they were telling the truth. And they got bad grades, so that "proved" to me that they couldn't see the board either and just didn't care.
I didn't have my eyes tested until my mother, sitting with me at a doctor's office, asked if I could read the eye chart that was on display.
7-year-old me: What eye chart?
Mom: The one over there on that wall.
Me: What wall?
Mom: That wall right over there, with the big poster with the random letters.
I got upset and cried. Why was my mother telling me the same lies that the kids in school told? It wasn't until then that she realized
I couldn't see it. There were a few dark blurs on a field of blurry white, and that was all.
