I know that because there were plenty of opportunities to view mermaids the next day when I hopped on the hotel's shuttle bus, was dropped in Piazza Barberini, with its Triton Fountain, and started exploring all my old haunts. And to my delight, I discovered that they don't call it the Eternal City for nothing: everything was exactly the same, even the bakery, Il Fornaio, where I used to buy a lunchtime slice of pizza,
only quite a lot cleaner. I mooched happily around the Piazza della Rotonda, admiring the ice-blue and terracotta-coloured Renaissance houses and the Pantheon with its miraculous dome, dodged the living sculptures in Piazza Navona (I'm sure I recognised a few from last time) and ended up strolling through the Campo de'Fiori to Palazzo Farnese to drink in its Michelangelo-designed façade. Here I stopped for a Campari and soda in Bar Farnese, a place I'd always fancied the look of but couldn't afford. It was just as good as I'd hoped, and well worth the wait. I'll be back again in another 20 years, hopefully for good.
