It is somewhat common in the US to use the "xoxo" - meaning hugs & kisses - as an ending or a signature. However, the " X " seems to be the British version of that. I never see the "O" in there.
So, given that this X tends to be used when corresponding with close friends, imagine my surprise when I received an email from a work client/colleague/acquaintance and HE ended his email with
There was no name, no "bye", no "regards", etc.
I was surprised and still am a bit perplexed....
I am wondering if I have the meaning of this signature incorrect??? Would you use such a signature or ending in a business setting?
