It looked like the Boy had made quite the mess in his room when I arrived home, but he quickly corrected me. “It’s a miasto!” he explained ever so patiently, as usual mixing his languages.

And it is indeed a city, or perhaps town — miasteczko, but he wouldn’t have said that — complete with fire and police stations, a construction site, and a hospital.

“That’s over half an hour of work!” K explained with a laugh when I got back downstairs. Half an hour of work, many hours of fun: it’s still up, several days later.
