Silently diagnosing people

I can't help but silently start diagnosing people when they say things that make me think autism or if I see them acting in similar ways to me. 

Is this something anybody here does?
My cousin Paige appears very shy, she rarely speaks, she never makes eye contact - I didn't realise this until yesterday -, she doesn't like overly bright things, she said this yesterday and then only just I said I was going to sort my books and she asked if she could come and help because she loves organising things.
And now my brain is trying to work out whether she has autism or whether I'm just seeing things that aren't really there. Or, maybe I'm just desperate for another autistic person in the family. Lol.
A part of me wants to ask her but I don't want to offend her in case she would find that offensive as I've sadly read a lot of people do.

  • I'm really bad for doing this too but with anything, not just autism. If there's something I've been researching in the mental health field i'll then see traits etc in almost everyone I meet. I try to keep myself in check though, I'm far from a professional and we never know the full picture of someone's whole self.
