Yes, we do seem very similar in that regard. I'm confident there are many of us out there! I was only assessed this year, so I'm still learning about the wonders of autism, myself. Have you been assessed?
For most of my life I would have said cats, but now I like both. I have a trauma support dog and we are so in love with each other (lol), I can't imagine my life without him. I'm not certain that I'd ever connect with another dog quite so much.
I currently have two cats as well as my dog, and I love them all.
Books or movies? (I'm a confirmed bibliophile. Essentially, all I do is read).
