I have never been so relieved to see a man in flip-flops holding a hosepipe as I was when we finally found Porto Corallo. The Sat Nav had given up somewhere near Villaputzu, leaving us to navigate by instinct and a rapidly dwindling phone battery. My instinct, it turns out, is terrible. We ended up down a dirt track between two fields of sheep, where an elderly shepherd named Tonino was watering his tomatoes. He looked at our hire car, looked at us, and said something in Sardinian dialect that I am fairly certain translated to "not again."

Through elaborate pointing and my embarrassingly limited Italian, Tonino explained we needed to go back past the petrol station, take the second left, and ignore the sign that looked correct because "it lies." He said this with the gravity of someone discussing a family betrayal. I thanked him profusely. He offered us a tomato. It was warm from the sun and genuinely the best tomato I have ever eaten, which felt like both a reward and a commentary on our incompetence.

Twenty minutes later we reached the actual Porto Corallo, a cluster of pastel-coloured apartments terraced into the hillside above a cove of improbably turquoise water. Our key was with the site manager, a formidable woman named Signora Fenu who operated from a small office that smelled of jasmine and photocopier toner. She inspected my passport photograph for so long I began to worry I had committed some crime I had forgotten about. Eventually she handed over the keys and a laminated sheet of rules that included, I am fairly certain, instructions about not hanging laundry in a manner that would "disturb the energy of the complex." I did not ask for clarification. Some mysteries are better left intact.

The apartment itself was simple and spotless, with a balcony that looked directly down onto the communal gardens. Within five minutes of arrival, I had met our downstairs neighbour, a retired accountant from Cagliari named Enrico who appeared to have appointed himself unofficial mayor of the terrace. He was watering his own tomatoes - apparently tomato cultivation is a universal Sardinian greeting - and immediately informed me that the previous British occupants had been "very loud about soup." I still do not know what this means. I did not ask. Enrico seemed pleased by my restraint and offered me a glass of mirto he had made himself. It tasted like liquid purple and friendship.

That evening we walked down to the small beach, where a man named Gavino was closing up his kayak rental hut. He was in no particular hurry, methodically coiling ropes while arguing with someone on his mobile about whether his cousin's new motorbike was genuinely a good investment. When he noticed us, he paused the argument without saying goodbye and asked if we knew that the water here was "older than the arguments." I think he meant something poetic about the sea. He then tried to teach me the correct Sardinian pronunciation of "Porto Corallo," which involves a sound somewhere between an L and a swallowed marble. I failed repeatedly. Gavino found this hilarious in a kind way, the way you might laugh at a dog attempting to play chess.

By the time we climbed back up to the apartment, the sun was dropping behind the hills and Enrico was on his balcony, conducting what appeared to be a conference call with three other retirees about tomorrow's bocce tournament. He waved. I waved back. Signora Fenu's laminated rules suddenly made perfect sense - not as restrictions, but as the necessary architecture for a place where everyone knows exactly how things should be, and will absolutely tell you if you get it wrong, usually while offering you something homemade and excellent.

I sat on our balcony with the last of Gavino's mirto, watching the last light on the water, and reflected that I had spent the entire day being gently, thoroughly, and very specifically helped by strangers who treated my incompetence as an opportunity rather than an irritation. The tomato from Tonino sat on our kitchen counter like a trophy. I had absolutely no idea what tomorrow would involve, but I suspected it would involve more conversations I only half understood, more unexpected kindness, and probably more tomatoes. I could not wait.
