I find it weird/funny you are getting so many hate responses towards Ed, still no counter-arguments at all. When asked why he is wrong, they vanish. From the outside it looks like a coordinated campaign to try to discredit him.
Happy to read why is he wrong, and change my mind, as long as the arguments provide the same level of analysis he provides.
Absolutely! Dogs use yawning a lot in their communication if you look close enough. They also have other messages like smelling around, looking away, etc. I think they all might mean something along the lines of "I don't see you as a threat to me so we are good"
