How do you teach banter to someone who doesn't get it?

Just replied to someone else, but I had a feeling the kid was autistic. As an autistic adult, I gotta tell you - you kinda can't teach it to an autistic person. I'm an autistic adult who fully understands, on a logical level, what "banter" is, I understand what it is and how it's done, I could describe and write a "banter" situation, but actually intuitively understanding where the line is in the moment when it's happening in real time, how to tell if someone is being insulting as "banter" or not, how to make my own replies both an appropriate level of insulting while also making it clear that I'm not being insulting, etc... there's no way of really learning that to the degree that a non-autistic person *just knows* it. It's still hit or miss for me as it is. I mostly get it right, but that wasn't the case for a long time. It relies on subtle social cues that are hard to notice even when you're manually looking for them (and taking a moment to analyse what someone might be doing can kinda make things awkward too). It relies on you communicating those same cues back to others, which is very hard to do when those don't come naturally to you. The performance of social cues (and lack thereof) is basically why autistic people are always read as a bit weird, standoff-ish, robotic, etc. We don't show the same external cues of our mood or intentions as non-autistic people do, because we're not wired to be able to understand them and internalise them so fundamentally that we do them without thinking. In short, you need to manage your own expectations. Help him understand how being autistic will make that harder for him than it is for others. And correct him if he tries to participate and ends up being too harsh, by trying to teach him the "rules", not by punishing him.
