‘Pretty much. Like the time I convinced a whole tour group that the Swiss are such incredible conservationists, they turn off their waterfalls at night to save water.’

‘You did not.’

‘I did. I had a whole spiel about the Swiss enlisting the Dutch engineers who had saved Venice by engineering failsafe flooding technology – and how they’d designed a way to redirect and harness the waterfalls to save water and generate energy at the same time. It was compelling stuff, my lies.’

‘But how do you know they bought it?’

I stopped walking to tell the rest of the story. ‘Because we were staying in Lauterbrunnen that night – it’s in this unbelievable valley – sheer cliff faces each side of these gorgeous rolling green hills – anyway, there are all these waterfalls that fall from the top of these super high cliffs to the valley floor, throwing up mist-rainbows everywhere – and it’s awesome. I mean, it’s probably the most beautiful place I’ve ever been to. On the planet,’ I added for emphasis.

His eyes widened, indicating he was duly impressed.

‘So, I told the tour group that the waterfalls shut off at sunset – around eight o’clock – and that it was a sight to behold. So, there they all are at ten to eight, cameras and phones at the ready, watching the top of the nearest waterfall, waiting for it to stop flowing down the side of the cliff, and I was playing along – I had my camera ready too.

‘And at eight o’clock, when someone called out the time, someone else said, “I can see it! Look! It’s stopping!” And there’s this moment of frenzy and they are all convinced something’s happening, and they’re taking photos and video footage. And I ran out in front of them and turned and took a snap of all of them looking through their lenses at the top of the waterfall.

‘And, then I fell about laughing. And slowly, one by one, they realised I had tricked them. And some of them thought it was cool and even really funny – and others were pissed off with me and stormed away ’cause they felt dumb.

‘Anyway, it was all in good fun. I mean, we were camping through Europe for six weeks together. We were like this oddball family on wheels, and we were always playing pranks. I wasn’t the only one, you know.’

‘I love that you got them to buy that whole thing.’ Josh gestured towards a road leading away from the square, and I nodded. We started walking again. ‘Was it a bunch of Americans? ’Cause I feel like most Americans – especially if they’re travelling – will believe anything.’

‘No – only a couple of Americans. Mostly Aussies and Kiwis – a couple of Canadians and a Korean couple. It did kinda backfire on me though.’

‘How’s that?’

‘Well, from then on, they didn’t trust anything I said – even the true stuff.’
