The girl has stayed alone at home. Her parents have gone out. She wants to relax and chat with her friends, but she also has to do many things in the house.
She has to make her bed, sweep the floor, tidy up the hall, do dusting, mop the floor, wash the dishes, water the plants, and dispose of the trash. Her parents are coming back now and will see that she's already made her bed. She hasn't swept the floor yet.
She's already tidied up the hall. She's already done dusting. What has she already done?
What hasn't she done yet?
