I would say I'm pretty smart, I have a job that relies on being intelligent and I excel at it.
My toddler and I are pretty much learning to read together. I didn't realize how much I stuggle to read, or at least read aloud, until I tried reading books to my son and it fucking rocked my world.
At first I thought the books were poorly written until I heard my wife reading a bunch of them without a problem.
Dyslexic maybe? I know a decent number of engineers who struggle sometimes even though they do medium complex maths and can remember long lists of standards or do a bunch of coding.
I always struggled in school, even though I generally understood all the concepts pretty well.
I do remember at one point being pulled from classes and read a book to a guy, then a week later being put in special ed. The special ed program got shut down and shortly after I moved and the new school was even more of a shit show where no one cared/had the capacity to single out one struggling student.
