Let’s have a look at this picture of our sitting-room. As you come into the room, you notice a piano, with a low music-stool in front of it. Next to the piano is a tall bookcase, standing against the wall. On the left is a large window. Under the window there’s a radiator, but you can’t see it, because it’s behind the settee. On the settee there are two cushions.

The fireplace is at the other end of the room. On each side of the fireplace there’s an armchair. An old lady is sitting in one of the chairs, but nobody’s sitting in the other one; it’s empty. In the centre of the mantelpiece there’s a clock, and above it an oval mirror. On the right you can see a standard lamp.

Opposite the fireplace you can see a small table with an ash-tray and some newspapers on it. By the table there’s a small chair. On the extreme right, there’s a radiogram. The floor is covered with a beautiful thick carpet. An electric light is hanging from the middle of the ceiling. At night, when it gets dark, we switch on the light and draw the curtains. During the day, the light comes in through the window.
