It begins with helping a man currently in Taiwan arrange UK trains and book in advance so it didn't cost a fortune and take hours (this has nothing to do with us, and it often irks when someone expects us, rather than say, a train company or ticket website, to help them. However, he was so bewildered, yet clear and patient, he was a delight to help.)
Then there was a phone call commencing "Hello, I'm calling from Afghanistan, and would like to arrange a visit in December. For reasons I can't explain, as this isn't a secure line, I won't have access to the Internet for a while, so can I sort things now? It'll give me something to look forwards to." Our answer was pretty much "yes to everything mate, Nd we really hope we see you in a few months."
A rather international day!
