It’s 10pm, and I’m chatting with new friends after dinner at a guesthouse in wilds of Catalonia. The candlelight flickers off stout terracotta jugs of wine and on to the faces of Thomas, a management consultant from New York, and Viktoras and Gabije, a charming Lithuanian couple I’ve been grilling about Baltic holiday spots. Ellen is German, living in Barcelona and training to be a therapist. It’s testament to the relaxed vibe that the conversation flows as smoothly as the wine.
