I have never been so grateful for a gravel driveway in all my life. There we were, my partner and I, crawling along what I had confidently described as "a scenic route" after misreading the satnav, when our little hire car announced it had had enough and deposited us in a ditch just shy of Tanumshede. The ditch was shallow, I should add, more of a grumpy depression really, but it was wet and it was undignified and it was absolutely my fault for insisting I knew better than Google.

A chap called Lennart found us. I say found; he was walking his dog, a enormous creature that looked like a wolf dressed up as a sofa, and he simply stood at the edge of the road watching us with the patient expression of someone who has seen this exact scene approximately four thousand times before. "Soedra Klaetta?" he asked, before I had even wound down the window. I nodded, sheepish. He nodded back, not unkindly, and produced a rope from his jacket pocket as casually as if he were offering a mint. Ten minutes later we were free, the car was filthy, and Lennart was refusing payment with a wave of his hand and the immortal words: "You will pay at the shop anyway. Everything costs there."

He meant the ICA supermarket in Tanumshede, where we stopped for supplies, and where I first understood that Lennart was not being cynical but merely factual. The woman on the checkout, Birgitta according to her badge, scanned our miserable collection of pasta and wine with the focused intensity of a surgeon. When the machine beeped at my foreign card, she did not sigh or roll her eyes. She simply reached beneath the counter, produced a laminated instruction sheet she had clearly made herself, and talked me through the Swedish payment system with the gentle thoroughness of someone explaining breathing to a particularly dim child. "You are staying at Soedra Klaetta?" she asked, having evidently spotted our address on the receipt. I confirmed. She brightened. "The owner, he is my cousin. He talks too much. You will see."

She was not wrong. The owner, a splendid man called Gunnar who met us at the property with a torch because we were two hours late by this point, talked for forty minutes straight before we had even seen the inside of the cabin. He talked about the granite bedrock beneath our feet, about the Bronze Age carvings just up the road at Vitlycke, about the best angle to view the sunset from the little wooden jetty. He talked about his ex-wife's new husband's boat, which apparently had engine trouble, and about how the previous guests had left the coffee maker in a state he described only as "criminal." My partner made coffee while I listened, nodding at what felt like appropriate intervals, and I realised gradually that Gunnar was not lonely or boring but simply generous with his time in a way that made me feel slightly ashamed of how guarded I normally am with mine.

The cabin itself was perfect in that unpretentious Swedish way, all pale wood and practical lamps and a kitchen that actually had the advertised six mugs. But it was the people that stayed with me. The next morning we walked to the lake, slightly stiff from the journey and the ditch, and met an elderly woman called Ingrid who was swimming in water I would have described as liquid ice. She emerged like a seal, wrinkled and unbothered, and informed us that she had been swimming there every morning since 1987 except for one Tuesday in 2003 when she had flu. "You should try," she said, not as a challenge but as a genuine recommendation, as if we were missing a free concert. We declined. She shrugged, pulled on a dressing gown that had seen better decades, and pottered off down the path humming something that might have been ABBA.

That evening we ate at a small place in Tanumshede, nothing fancy, just meatballs and potatoes and that particular Swedish contentment that comes from knowing exactly what you are getting. Our waiter was a young man called Anton who was studying to be a marine biologist and who spoke English with the flawless awkwardness of someone who had learned it entirely from American television and was now trying to correct himself in real time. He apologised for saying "you guys" three times during the ordering process, each apology more anguished than the last, until I wanted to hug him and explain that I had once asked for directions to "the toilet" in Texas and nearly caused an international incident.

By the end of our first full day, sitting on that wooden jetty with the wine we had bought from Birgitta, watching the light do complicated things across the water, I found myself thinking about Lennart and his rope, about Birgitta's laminated instructions, about Gunnar's magnificent inability to stop talking, about Ingrid's Tuesday in 2003, about Anton's linguistic crisis. I am not normally someone who chats to strangers; I am British, after all, and my default social mode is apologetic evasion. But there was something about this corner of Vastra Gotaland, something about the way these people simply assumed connection was worth the effort, that made me want to try harder.

The ditch, I decided, had been worth it. Though I did not share this thought with my partner, who was still occasionally mentioning the gravel in a tone of quiet trauma. Some reflections are best kept to oneself, or at least saved for when the wine is better and the memory of the wet has faded.
