In Tandem.

It is a long story!
I had to take my iMac in to the Apple Store in Kingston for repairs. As I trundled the heavy and ungainly load on a little trolley through the insanely crowded streets of Kingston, feeling foolish and a bit like someone carrying their wares to the Antiques Road Show, I was relieved that it was a computer, and not a Grandfather Clock.
Before I unloaded the Mac from the car I nipped down to the riverside with my camera, and was so grateful to this pair of swans  who flew by just as I got there. Blip done!
PS Mac needs a new hard drive - at least it is repairable.
