Who let the door open?
Who ate all the apples from the basket?
Who threw the flower out of the window?
Who put the vase in the cupboard?
Who broke the mirror in the drawer?
Who messed up my papers in the file?
Who took the books from the bookshelf?
Who spread the water on the floor?
Who hid the basket behind the sofa?
Who had received the letter from the postmen?
