Sounds like she was just lazy in school and so where her parents and teachers. Is she going to sue her parents too? We didn’t leave it all up to the schools when it came to our kids education, they already were reading and knew the alphabet before they went to kindergarten.
Even someone who would have managed to pull off the kind of feat she did would at least have some degree of curiosity as to what all those letters and words did and would be able to piece it together eventually. This reads like a textbook case of dyslexia. The learning process is there, the processing difficulty is solely in the written word.
