Helen, thank you. Understanding you edit, I have no remaining disagreement with your original post.

http://www.plagiarist.com/poetry/?wid=511, whose ending I quote here, may set the right tone:
So mind your manners when a native, please,
And doubly when you visit
And between us all A rapport may fall
Ecstatically exquisite.
One simple thought, if you have it pat,
Will eliminate the coroner:
You may be a native in your habitat,
But to foreigners you’re just a foreigner.
