Where does Prieto remember that he and his sister went after his father died, and what did they do?

Prieto remembers that after his father died, he and his sister went to Shore Road. They brought two forties of Heineken. They told one another every good thing they remembered about their father so they would each have their own memories and more. Olga was only 16. She got so drunk that Prieto had to carry her back to the car.
