The picture shows a woman sitting on a couch and reading the ista heating bill. She has long blonde hair and is wearing black glasses. Her top is a blue shirt and she is wearing brown trousers. While she holds the heating bill in her left hand, her right hand rests on her chin. She looks directly into the camera. The beige couch on which she is sitting stretches across the entire lower third of the picture and has a white blanket draped over the back on the left with a yellow cushion leaning against it. In the background are various pieces of furniture that suggest a living room: A floor lamp and a shelf can be seen on the right, and in the centre an open two-part door leading into another room with bookshelves. The entire background is blurred.
