DS always loved being read to. At not-quite-two I heard him chatting to himself, then realized it had cadence, then realized it sounded familiar. I peeked around the corner to see him reciting How The Grinch Stole Christmas, turning the pages at the appropriate time. He knew all his letters and sounds. But he didn't actually read. Halfway into first grade I was getting ready to ask his teacher about his lack of reading ability, when "click" he was off and running.
