Oh, they are totally unhinged, regardless of whether or not they’re doing crimes against statistics along with all their other crimes.

That unsustainable culture she’s talking about that we’re known for? Xenophobia and White Supremacy.

We head to the airport in a couple of hours, after a lovely (if too-short) Cape Town visit. It's a privilege to be able to travel 7900 miles and spend time with a BFF in gorgeous surroundings and perfect weather, and we're already looking forward to a return visit in the future.

Ringo Starr is the answer you might expect me to give, but my true interim answer is Bill Murray, I think.

I named my fists John Lennon and Paul McCartney because they're going to be surprising you with hits decades after you expect them.

Belatedly (and shamelessly) realizing that I have explored this particular subject before in the past.

Backgammon is a fucking awesome pastime, and I've had enough wine to say that those of you who don't know how to play backgammon are poorer for it.

“Yoo-was-ee-ans” is, I think, how most Americans would think to pronounce it, which almost none ever would care to do.

Band just asked us if we were “ready to rock”, and I realized that the truly transcendent bands do not ask if one is ready to rock—they instruct the audience that they are in fact ready to rock, and then they rock them.

Cheers to all that. :)

Bandshell in the distance, with musicians performing. A screen saying Jesse Clegg hangs behind them. In front of the bandshell are thousands of people, with trees lining the spectators’ region.

Three people smile for the camera, two sitting on camp chairs among flowers, the third sitting in front of them on a blanket.

Gorgeous evening here in Cape Town, Jesse Clegg is two songs into his set here at Kirstenbosch. I saw his dad in Cambridge back in 1989, so it’s making me feel a bit old. But the thing they don’t tell you is it’s not always bad to feel old. :)

<picks up fresh local nectarine, looks out at the sun-washed vlei stretching out toward Table Mountain, palm trees swaying from a gentle sou’wester>

The nectarines are particularly tasty this week.
