An autistic person is bothering someone and is unaware.
A neurotypical person sees the interaction and pulls the autistic person away.
Meanwhile, no explanation of what the autistic person was doing that was bothering the other person, and no explanation of how the neurotypical person knew that the other person was uncomfortable.
And if the autistic person asks what they did wrong, they’re considered rude.
No one cares about helping autistic people understand anything. People only care about saving the poor neurotypicals from the inconvenience of being in an autistic person’s presence.
