I used a little Greek with my Greek-born doctor!
She seemed really pleased. She said, I can't believe I'm talking with you about this here. By here, I think she meant in a country outside Greece.
I think it helped me get her to nicely agree to let me get a different test instead of a second mri. I did not want a second mri. Last year I said I did not want a second one and she insisted. I just never did it. So of course this year she requested for me to do it again.
But THIS year I told her in Greek that I don't want a second one and instead of insisting, she asked me why. I explained why in English and she was really cool about it. She said, ok, well, there is another test we can do and if those results are good, then you don't have to get the mri but if those test results are bad, then you really need to get it.
I totally credit charming her with a little Greek as the reason that she was willing to compromise with me about this matter. So yay for Greek!!!!!
I have had such reactions from speakers of several languages. Even my being able to recite the first proposition of Εὐκλείδης in Greek made the day of a Greek deli counterman I once bought lunch from.
