The tied-up curtain in the foreground creates the impression that the viewer is looking at an intensely private, personal scene. There is also an element of "trompe-l'œil" as Dutch paintings were often hung with little curtains to conserve them, and the device of painted curtains is seen in other Dutch works of the period. The diagonals on the chequered floor create the impression of depth and three-dimensionality. The fact that it is a love letter that the woman has received is made clear by the fact that she is carrying a cittern, a form of lute used in the period as a symbol of love - often carnal love; "luit" was also a slang term for vagina. This idea is further reinforced by the slippers at the very bottom of the picture. The removed slipper was another symbol of sex. The floor brush would appear to represent domesticity, and its placement at the side of the painting may suggest that domestic concerns have been forgotten or pushed aside.
