I am a native French speaker who had a phase with an interest toward grammar, so I probably can help you with it if you are learning this language. Also I am quite good at explaining maths to kids or teens, even those with difficulties. It gets harder with adults.
I do care. I totally get how you can be charismatic in school despite being autistic, that is perhaps the biggest misconception. I personally think if I had no morals and just wanted to make money my best bet would be running some kind of cult (but that would be wrong ofc).
