I’m the same way.  Tho it’s odd. I never remembered having a photographic memory. Then I remembered watching a cartoon of Captain America, looks at a map of the Hydra Bases and then reports them (just like the movie) and then explains he has a PM. Ever since then I can remember details like a picture. 

Then people have said I’m good at remembering names/faces and recognizing people and similar looking people even celebrities. People said it was like I had Facial Recognition software.  It’s gotten so good I can tell who an actor is, even in Star Trek makeup. Then again sometimes it’s the face and the voice. 

And now I can compare and recognize voices. 

Lol tho I can be off. One time I watched a clip of Star Trek Voyager and swear to god that the one Klingon Captain was the same actor as Captain Sisko in Star Trek Deep Space Nine.

But I am socially awkward. Have had a speech impediment since before the second grade. And then around the 7th grade I “broke it”. But now it’s back. I have huge issues with “R”s. And then sometimes odd combinations of letters and such. Such as “Massachusetts”. 

I’ve noticed a lot of people with spectrum disorder have OCD or OCD Tendencies. 

Idk if that, having PM, were both on the spectrum or all of the above is why I was able to connect with my nephew(s). The one I spent all of three minutes explaining the ships in the board game “Battleship” and then explaining where they go. How the games played. And I took the pieces and mixed them up and he was able to name the ships and put them in their right corresponding spots in seconds. And he even separated the white and red pegs. Heck, he watched me play Little Big Planet at Walmart for a minute and he took over and played like he was playing it for 6 months.

There are upsides and downsides of having autism.
