Reading A Short Story Collection by a Swiss Author and Remembering

this dinner I had in Lugano, in southern Switzerland, which is basically Italy. It had just become summer,  and we were eating outside. Across from us was a large group of teenagers who had all the beauty and none of the awkwardness of youth. The girls and boys were all moving around their long table, and flirting madly with one another. It seemed to be a night they wouldn’t remember, because that summer would have many nights like that, all out together, the sun not setting until late, the evenings often ending with a darkened swim in a lake. This was more than ten years ago; I was a teenager then, too. I wonder where they all ended up, if any of their pairings or friendships stuck, if they had to grow up and quit smoking cigarettes.
