Alright - I'm an American girl corresponding via email with a British male. This began quite simply - regarding his book, and - we've had a few exchanges at this point. [Still dancing that fine line between academia and personal].
In general he closes his emails with "With kind regards" etc. and recently moved to "With all good wishes,".
I know I've no real reason to hope that this is anything more than simply a conversation, but - that said - are there any closings I could perhaps use which might up the ante, so to speak - without scaring him off?
I would be much obliged! Thank you!
Kind regards,
K.
