I found out that I will need to travel abroad at my work, and it really took me off guard.
human
Wow, that would be shocking if you weren't expecting it.  Did they tell you when you were hired that there was a possibility?  Where might you be going?
human
No, they didn't tell me, but I did suspect it might be in the cards. I'll be going to South Korea for a while.

That will be very different.  How do you feel about it?  I wish you lots of luck and adventure while you're there!

I feel confident since I have been there before on holiday. Thank you very much!
