What was the familys reasons to by attila In story of rk narayan?

There is no mention of a family buying "Attila" in any of R.K. Narayan's works. It's possible you're thinking of a different story or author.

Could you please provide more context or details about the story you're referring to?

Perhaps you could tell me:

* The exact title of the story or book.

* Any other details you remember about the story, like the characters involved or the plot.

With more information, I can help you find the answer you're looking for.
