The third word: buenas tardes – good afternoon. This time it is buenas, not buenos, and that is exactly what the story is about.
You can feel lunch in your stomach, so it is after midday. You are reading the book about elephants again, but water was spilled over it during the meal: the book is now wet (buenas) – last time it was nostalgic. There is also a bit of steak tartare left on the book from lunch and next to it a piece of dessert (tardes).
