I don't think you get the full picture from one little story, and everyones experience is different, but from my experience what is striking is that because they see the world differently, their observations are different and often when we hear novel observations of the world it seems really "intelligent". If you capture those moments in a story because they are interesting, you aren't capturing the other things, things like their stims (repetitive behaviors / noises), how they react to noisy scenarios, other people, physical sensations etc. Its just their observations of the world are often interesting, or even physical things that seem hard for us (like from early on once my son could write his full name, you could keep rotating the paper around while he writes it and he'd keep writing his name such that once rotated back the right way everything looked correct)
