Earlier quoted context omitted.
Curious how this trait is American? Is there something about the way Americans speak that is fake?
Yeah, absolutely. At least to my British ears, Americans rarely sound authentic. Its always grandiose statements and elaborate smiles.
"I may be wrong", but perhaps 'Americans rarely sound authentic' to you simply because you're just more familiar with your own culture's idiosyncrasies?
Anyway, I love the Brits; no flame intended. I come in peace! :-)
