Dubai spread out at the my feet in a dusty, glittering sprawl, with the world's tallest building, the Burj Khalifa, just visible on the hazy horizon.
Fabulous white boats were moored in the cove below and, off to the left, a public beach with sand as white as the yachts.
After a staggeringly good lunch it was time for some touring so off we went for a close-up look.
The reason - the baking, holy-hell heat of the place.
The only way you could sit on this beach for any length of time would be under some shelter. Hence the reason for that solid blue tent in the foreground. It's a bit weird when you think about it... someone under the vast blue, utterly cloudless sky had to shield themselves from the blistering sun with a semi-circular 'sky' of protective fabric.
We were talking about the many nationalities who live and work in Dubai. Her strategy for calming any tensions is simple. She asks, "What colour is the sky in your country?"
Blue sure has its soothing side. It's all about one-ness.
But it can also speak of yearning. Some of my fave few lines of poetry are these. They speak of how prisoners feel when they glimpse blue from a barred window...
"I never saw a man who looked
With such a wistful eye
Upon that little tent of blue
Which prisoners call the sky... "
It's a tiny part of Oscar Wilde's Ballad of Reading Gaol.
In a recent biting monologue, comedian John Oliver talked about how predator drones have made clear sky a sight that some people in the world look up at with dread. "Congratulations," he shouted to his audience. "We've managed to make one of the last remaining symbols of pleasantness – blue sky – completely f**** terrifying!"
I know that's true because I also met a Pakistani driver in Dubai who'd moved his whole family there from North Pakistan. They were desperate to get out of an area where drones were a constant threat. "When they come down," he said. "they destroy everything for half a kilometre around."
And there's the blue sky that simply makes us feel happy. I've read a few online messages lately from Amanda Harrison, Britain's only female commercial Tiger Moth pilot, who is in her element in open air up amongst the clouds.
For everyone else in the world, signing off is a standard sort of routine. "Regards", we say, or "Cheers", or "Best wishes", or "Ciao". For Amanda, it's a cheery,"Blue skies!". That's more the kind of blue we want to know and love. Even on a grey day, it's an idea to lift your spirits.
