It was his old friend. They had not seen for several years. It seems they studied together. They speak very cute. They remember mutual friends. Leo says he's gained weight by 20 kilograms. His friend replies that also gained 10 kilograms. Leo says that since she was very skinny, then an additional 10 kilos went to her advantage, and she is looking very good. Apparently sometime they were close, but had longe parted.
In general, a nice conversation between two old friends.
