Eric, Graham:
I think I know the expat to whom you refer, Eric, and yes, he is hard to find. I tried doing it on Wiki, and it would have us believe that he's an actor as well as a photographer! It doesn't even get close to the chap I have in mind: nothing, including those mythical Wild Horses (pace Stones) would get him onto a stage. He told me that once, when he was about fourteen and had no choice in those matters, he was obliged to go forth into the limelight and deliver a poem. Never again! I suspect it was the source of his later heart attacks.
Regarding the brevity of external relationships: I believe that if married, one should never look back, and certainly not forwards, but I haven't read anything about looking sideways. However, Ms Coke is a pretty confident chick, so I don't think she'd be upset were the contents of a distant relative considered, but hey, no way another container would be permitted to grace a particular lens. There are limits to open relationships too, you know!
