I had another of my surreal days yesterday. The hour between 2pm and 3pm was particularly strange.

While trying unsuccessfully to hook up his computer to a malfunctioning T-Mobile hotspot I found myself discussing American politics with a 52-year-old Californian corporate attorney who looks like Dubya and rides on private jets but is, mercifully, a registered Democrat who invests in eco-friendly businesses.

In Starbucks.

In the City.

Next to her…

…as he walked by…

“Nikki from Big Brother 7” – as I believe she used to be known – is a testament to the abilities of Photoshop (she has appalling skin), reads Jodi Picoult novels and has a picture of a nice black and white collie as the wallpaper on her Nokia N95.

Yes, it seems she really can read.

After she left, I informed my caffeine-imbibing companion that we had been graced by the presence of Celebrity.

“Who was she?”

“She was a Big Brother contestant a couple of years ago.”

“Ha! I take it she didn’t win, then?”

Touche.

Dexter Fletcher, meanwhile, was wearing a very sharp whistle. He looks old, but then he’s always had a face like one of those dogs with all the creases that look like Steven Gerrard.

All this comes four days after almost knocking over Ronald Pickup at a train station. He’s nearly 80: even I would have felt bad about that.

And so to 48 hours of completion. I suspect I’m going to miss out Thursday and Friday and come up grimacing on Saturday.
