They say you can’t go back. And for a long while, I didn’t. I hadn’t been back to Britain, since we were married in July 2002. It was a combination of factors: kids, jobs, exchange rates, etc. I hadn’t seen my parents either: I had explained to them that planes fly West as well as East, but they preferred to spend their holidays in Sri Lanka and Thailand, rather than Arizona. [I reckon they are actually senior citizen agents for MI6, because wherever they go somewhere, internal turmoil seems to follow] But 2010 was their 50th wedding anniversary, and when we got the invite, filial loyalty kicked in: time off work was booked, plane and train tickets booked and arrangements made to handle dogs, kids and mother-in-law left behind.
