That's my parters special interest too!
They mentioned a few times that they weren't the type of autistic that had a special interest and/or was good at any one thing. And I was like, you really dont know do you? I've heard them giggle about people 'bragging' they had read 65-100 novels that year. Which to the average person I agree is a ton, but I am sure 600 isn't even an exaggeration about your wife because I wouldn't put it past my partner for doing so!
My main special interests are art and plants/nature. Those come in many varieties. I like painting & drawing, crafts, sculpting, sewing, embroidery, and beyond! I go through spurts of each and cycle back, never knowing how long I will be hyperfocused on anyone thing. Plants has been a big one for atleast 5-6 years now. The problem with plants though is that when the hyperfocus ends you still need to care for them and sometimes it burns me out, but I always come back to it.
Music use to be a huge one for me growing up. I've been told I know a lot about music history and remember so many songs and lyrics but it doesn't feel like it because I have heard so many more songs than I do remember so in comparison it doesn't seem like a lot. I use to play a variety of musical instruments too. Started with a keyboard went to bass then guitar then ukelele and mandolin, dabbled in harmonica and the spoons even! But Ive moved so many times in the last 15 years that hauling instruments that I played less and less became a chore.
I also love my two Shiba inus, and animals in general. I use to bring home stray cats growing up and at one point had five cats. I have one of them tattooed on me too.
It was distressing attempting to condense my interests.
I think if I talk to much I can become overbearing or appear self-centered. I worry too much about what others think and perceive me as which in itself could be a special interest I imagine.
Stray cats are the best! My partner's cat after two years is now finally fond of me. I am usually good with cats so I just gave her space, would give 1-2 pets here and there when about to give her food or water when she seemed open to it but not that often because she would try and bite and swat. But now she honestly won't leave me alone some days and is very needy. My partner even seems jealous sometimes I think because all the animals now love me best. Which I don't feel sorry for, being their #1 rocks.
Animals and art! Occasionally I get super hyper focused on one kind of creature or technique, but my fav changes constantly. Except for my cats, they are top bois 100% of the time
Knitting has been a special interest for years. I tend to find a specific thing, and make lots of them, before moving on to the next thing. The last one was hats. All different kinds, different types of knitting, and fancy patterns after I started learning fair isle. Now, it's socks. I'd never knit a sock before until the one I finished yesterday, but there will soon be so very many socks. I don't even like wearing knitted socks because I hate the texture under my feet. Strange thing for me to fixate on!
