In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example input: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Example output: How many books are there in the British Library?
Example explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.
Q: Article: On one of her trips to New York several years ago, Eudora Welty decided to take a couple of New York friends out to dinner. They settled in at a comfortable East Side cafe and within minutes, another customer was approaching their table. "Hey, aren't you from Mississippi?" the elegant, white-haired writer remembered being asked by the stranger. "I'm from Mississippi too." Without a second thought, the woman joined the Welty party. When her dinner partner showed up, she also pulled up a chair. "They began telling me all the news of Mississippi," Welty said. "I didn't know what my New York friends were thinking." Taxis on a rainy New York night are rarer than sunshine. By the time the group got up to leave, it was pouring outside. Welty's new friends immediately sent a waiter to find a cab. Heading back downtown toward her hotel, her big-city friends were amazed at the turn of events that had changed their Big Apple dinner into a Mississippi. "My friends said: 'Now we believe your stories,'" Welty added. "And I said: 'Now you know. These are the people that make me write _ .'" Sitting on a sofa in her room, Welty, a slim figure in a simple gray dress, looked pleased with this explanation. "I don't make them up," she said of the characters in her fiction these last 50 or so years. "I don't have to." Beauticians, bartenders, piano players and people with purple hats, Welty's people come from afternoons spent visiting with old friends, from walks through the streets of her native Jackson, Miss., from conversations overheard on a bus. It annoys Welty that, at 78, her left ear has now given out. Sometimes, sitting on a bus or a train, she hears only a fragment of a particularly interesting story.
Answer: Two strangers joined her.
A:
What happened when Welty was with her friends at the cafe?
