How would you translate "Is this a bad time to call?" in Korean? My company is currently preparing a presentation for Korean clients. On one of the slides, it has to be written "Is this a bad time to call"? Using "bad time" is very important here, because we're trying to get people to answer NO. The problem is that our translators wrote "지금 잠시 통화 괜찮으신가요?" and the logical answer to this is YES. I asked a Korean person what they thought and they said I should write "지금 통화하기 불편하실까요?" but I'm not sure it sounds very natural? Korean friends, what do you think? Is there a more natural way to say it so that people answer NO? Please help me~

Writing a mail Hi, I need some advice. I have to write a professional mail, but I don't really know how I should start and end it. I don't know the person whom I'm adressing, so is it correct to use "Dear Mrs. Name"? As for the end, does "yours sincerely" work or is there anything better? Also, can I say "my associate Mrs Name" when talking about someone I'm working with?

Should I use さん or ちゃん if I am adressing someone I want to be casual with? I have to write a letter to someone I am going to put up. So I need to be casual and not too formal but I don't think I can use ちゃん because it's probably too casual... What should I do?
