I (21f) have an autistic best friend that I’ve know since we were in the 2nd grade (21m). I have ADHD, so when we were younger, we were like the only friend that the other had on account of our respective conditions making us quite an acquired taste. Recently, I’ve graduated from college while he is still in college, and I live at my own apartment while he still lives with his parents for free. Sometimes I worry that our maturity levels are just different now, because I feel like his pettiness comes out at the weirdest times. So, there’s a somewhat popular show that he’s obsessed with; he sends memes in the friend group chat about it, talks about it nonstop, etc. Without revealing the show, it’s something I would never organically watch, which I told him politely when he recommended it to me. I thought he would just be like “okay, that’s fine” but he got extremely offended and kept wheedling me to watch it. I still politely resisted. One day while we were hanging I hovered over a YouTuber I really like, and when he asked I admitted I was a huge fan. So, he went out of his way to talk bad about the YouTuber and basically make fun of my tastes. When I called him out for his random malicious behavior, he admitted it’s because I won’t watch his show. I’m so confused. Why is he being such a petty person about this? Should I just watch the show even though I doubt I’d enjoy it or just confront him? AITA here? Edit: The show is “The Amazing Digital Circus” since many wanted to know.
