How would you explain the Spanish phrase in the context? Mother says a casa chica means probably his wife knows about her but doesn’t mind, because a Small House doesn’t cost too much. The maid doesn’t even sleep here, no room. The water closet and gas cooking eye are in the same room. The main kitchen is downstairs in the bakery, passed through from the street, with a key. No library and no garden here, in a city that stinks of buses. Mother thinks it is all wonderful and reminds her of childhood, even though that was a long time ago and not this city. And if it was so wonderful, why did she never go back to see her father and mother until dead? How would you explain the Spanish phrase ‘casa chica’ in the first sentence? Thanks!
