I’d say it’s when it becomes uncomfortable to the other person. So if you’re doing something, but they can get over it, then they’re likely to chalk it up to you being you, but once it goes too far then it gets weird. But it’s not just related to neurodivergence, I’d say it happens for all things, like if someone eats a weird thing or wears too out-there clothes then it moves out of the “yeah, whatever” to “oh, that was a bit weird”.

Because of this, it also depends on what “normal” is to the other person.
