I'm an extroverted introvert type when it comes to my ADHD. I used to be much more extroverted than I am now. I had a good group of friends in high school, and a lot of off-on friends because they'd get sick of me routinely.
However, there was one friend who was also ND. If you got us in a group together we would go on and on, way too oxerexcited to care about anything else. My friend would get jealous of me "monopolizing" her, because "she was his friend first". My ex-girlfriend would get jealous of her because it seemed like I got along better with her than my own gf.
Everyone thought we were perfect for each other. Everyone thought we were secretly having an affair. The truth is we were two ND that understood each other in a school full of people who believed ADHD was fake and an excuse to be lazy. We were the two most hyper and flighty people in our entire school.
Did she wind up having a crush on me? Yes. She later told me. Before that, though, she once handcuffed us together and had us walk around town, I sorta figured it out then. Did I have a crush on her? Also yes. But in the end we understood that it couldn't work. Her plus me equalled absolute pure chaos and sometimes not in a good way. We ran in two completely different groups and worlds.
It was nice to have someone who was just as "annoying" as I was though.
