Literacy or Just Reading into the Details?

Growing nostalgic in thought, I recall my first encounter with a book I once claimed to be able to "read." I remember my mother would read this book over and over with me; sounding out each word and pointing with emphatic voice and facial expressions to match each part of the story line. I was asked to repeat after her, and point to words too. I realize now my mother was aiming to develop my literacy skills. I was no more than three years old at the time, when while my family was eating dinner, I opened that very same book and began to read it. Word for word I knew the story, inside and out. My parents and siblings cheered with pride for by literary success, only to find I hadn't yet turned the pages. They realized I could not read, that I had only memorized the book. I wondered was this the beginning of literacy for me, or did I just have a keen ability to read into the details?
