what does "rooms were paired"here mean?
All the rooms were paired. There were pictures on the walls, painted on the paper, with gold frames complete. Red carpet covered all the floors except the kitchen; red plush chairs in the drawing-room, green in the dining-room; tables, beds with real bedclothes, a cradle, a stove, a dresser with tiny plates and one big jug. But what Kezia liked more than anything, what she liked frightfully, was the lamp. It stood in the middle of the dining-room table, an exquisite little amber lamp with a white globe. It was even filled all ready for lighting, though, of course, you couldn't light it. But there was something inside that looked like oil, and that moved when you shook it.
