Yunior and Lola are living in separate apartments in the Heights in New York.
They're boyfriend and girlfriend, but they aren't doing so hot. They talk about once a week.
Yunior keeps cheating on Lola. Oh, Yunior. You finally get the woman of your dreams, and you can't keep it in your pants? Come on.
While Yunior is home one week, Oscar rings his doorbell.
For once, Yunior seems really excited to see Oscar: "I waited for him in the hall and when he stepped out of the elevator I put the mitts on him" (3.preface.2).
Then Yunior starts rolling a blunt to celebrate their reunion, and Oscar agrees to smoke a little. But he doesn't want to cloud his head.
Oscar looks thin, but Yunior thinks he's sort of at peace.
So why the out-of-the-blue visit? Oscar is really there to borrow some money from Yunior. He says that he's got a line on an apartment in Brooklyn and needs some money for the deposit. (Which is a big, fat lie.)
Also, he tells Yunior that Lola loves him and that Yunior shouldn't have slept with that Paraguayan girl. (Which is not a lie at all.)
Oscar says that he's got to head out; he's got a date in Paterson. (Which is also a big, fat lie.)
