I am 24, I have been in my job since graduating, and while I am well settled, I don't want to live here for the rest of my life and so I am looking for a job abroad. I have a group of friends that I get on well with, but they are all well settled in the area. I have kept my job search secret from them so far, as it is not yet definite, and I feel bad for what will be taking the conscious decision to leave them. I would have preferred to be able to tell them when I have accepted a job offer, which will help me explain my motivation behind the move.
We're all going away on a week long holiday together soon and I am likely going to want to take phone calls from potential employers and/or take the opportunity to do a more lengthy phone interview during the trip.
How do I bring this up and tell them that I am looking to move away?
