Dyslexia can be subtle; such as a person may read very well, but not remember what they read. Or, it can be profound when a person is unable to recognize a letter or attach a sound to that letter to make a word to link into a sentence and understand meaning. It shows itself differently from person to person.
You are invited to forget everything you know, well, everything you think you know about how we learn to read. Traditionally all of us learned the alphabet, letter sounds, words, word meaning and understanding of what we read from our early elementary teachers and family. We learn to speak by observing others. We learned to walk from determination and curiosity.
