The picture shows a relaxed scene in which an elderly woman is sitting comfortably on the floor. She is turned sideways to the camera and leaning slightly backwards against a white cupboard. Her right arm is bent while she holds the tablet in both hands and touches the screen with the fingers of her right hand. The woman is wearing glasses with red frames and a blue and white striped shirt. Her hair is short and blonde and she smiles as she looks at the tablet. There are several green plants in pots in the background. The largest plant is at the top left of the picture, right next to a window. This window allows warm, natural light to stream into the room, creating a cosy and bright atmosphere. Further left in the picture, closer to the foreground, a smaller plant can be seen, which is slightly out of focus and contributes to the warm atmosphere. To the right of the woman, in the background, other blurred plants can be seen, giving the room a fresh and lively look. These plants are at different heights and distances from the camera, adding depth to the image. The woman is sitting in a slightly bent position, with her legs drawn up and crossed. The overall effect of the room is inviting and cosy, which is enhanced by the warm light and the green plants.
