Funny thing Normally when we write email to someone we always put "Dear xx" for polite. Last time when I was working, I am trying to solve some problem out. I wrote so many emails to one of our business partners. This guy was helping me out in a very bad situation and I was so glad, so when I wrote back email to him I put 'Dearest xx', before I click the 'send', I thought for a few seconds that might be not appropriate. However I just tried to butter him and thank him so I sent out the email. Then after 5 minutes he rang me back directly to discuss the work thing, then afterwards he laughed and mentioned that I used 'dearest' and he said his wife would...I felt so embarrased and said sorry to him then we both laughed. Gosh! But believe me, since that day, we always write emails for the working but more closed and friendly (I can tell from the word he used).Haha...
