Please don't be unkind to people whose accents aren't English. My son fell in love with a girl he met in central Russia when he was travelling - they moved heaven and earth to be together, applied for all the right visas etc and did it properly, got married, applied for all the right things etc all of which cost thousands of pounds.
She sailed through her Citizenship exams and applied for and has been granted British Nationality and has a British Passport. My son is so proud of his wife. During this time she's held down a full-time job and passed an MSc in Economics (paid for by themselves out of their hard-earned savings).
During that time she doubled the sales of the small British company she works for and her employers are very pleased with her. Yet so often, when someone phones the company to place an order, they are rude to her about her accent - some refuse to speak to her and ask to speak to someone English and some put the phone down on her. She speaks very good English indeed - she does have a Russian accent but it is no more difficult to comprehend than a Devonian, Welsh or Scottish accent. It makes her so sad that people are unkind and judge her as some sort of unfit person and refuse to let her do her job, just because of her accent.
She is thousands of miles away from her mother and doesn't see her very often, and I try to be a mother as well as a mother-in-law and it's so awful to have to apologise for the rudeness and intolerance of my fellow countrymen and women.
