Do you think “neurotypical” people love dealing with random people’s opinions and needs?
Disliking a suit and tie isn’t some revelation to “normies”. You are not a radical for thinking that. In fact, all the little things that annoy you probably annoy other people too.
This is a clue to easy small talk. Just say that something annoys you. “Oh man, this suit is murder in this heat.” It’s easy.
Either the answer will be “Yeah man, heh” or “nah, I like it”. You have now successfully engaged in small talk.
You know the answer to this. Because the CEO at your company sucks but you still need the money. Many people, even those in your industry, do not wear suits at work. I guarantee it.
