What a brilliant question! All feature films would have a maximum run time of 30 minutes. All books would have a TL;DR at the end. If anyone takes longer than 5 minutes to explain a simple concept, they owe you a dollar. Neurotypicals would be highly incentivised to work as diary managers and time keepers for us. Forgetting what you are about to say just as you launch into a great speech would be considered good luck and there would be clapping and hugs. Commas in sentences would become optional. If a Neurotypical stops responding to your text messages half way through a conversation until a week later and then pretends they didn’t just trigger a week long RSD anxiety attack - straight to jail.
