I'd previously gone out for a bite to eat and a coffee with her, see if we could be friends (certainly nothing more - I live in a country I don't speak the language of, neither do I have any friends or family here - I'm in total monk mode - I thought I could learn the language, trying to converse with her.)

She could make no conversation except for her fascination with "Craniosacral" quackery. I emailed her that I believe in truth and she believes in falsehoods and scammers and I can't have such people in my house.
