We communicate with each other verbally and non-verbally. To maintain a reasonable rate of information flow from talker to listener, non-verbal handshaking from listener to talker is used for flow-control.
Unfortunately, people with an Autism Spectrum Disorder (ASD) like me (I was officially diagnosed as having an ASD, yesterday) can't detect non-verbal handshaking, resulting in failure to communicate. Body-language = Double-Dutch. This is confusing and upsetting for all concerned, because neither the talker nor the listener understand what's going on.
A talker with an ASD thinks "Why won't they listen to me?". "Why are they walking away?", while a listener without an ASD thinks "Why do they keep on talking when I'm giving clear signs that they should stop?".
Like SkyNet, I have become self-aware. Now that I am aware of this problem, I can fix it. Here's the solution. If you're having a conversation with someone, and they don't stop talking when you're giving clear signs that they should stop, do the following:-
Oh, look. The French already do it. From the above site:-
"Chut! / Silence!
When you want some one to shut up or fermez-la, you can hold up your index finger in the air (not in front of your lips), and give a severe look to the people disturbing you. French teachers use this gesture frequently."
Please don't give us a severe look. We don't do it on purpose to annoy you. We can't help it. TIA. :-)
