Apparently it was yesterday according to this post but I had it in my mind it was today. Oh well.
One year (and one day) ago I was stumbling around Heathrow and then Holborn, shaking off the sleep and adjusting my internal clock to my new home.
And what I said in the linked post still holds true: it's good to be back. Wouldn't have traded this last year for the world, and the coming year will be even better!
