Mrs. Sawyer is at the shop now. She wants some school things for her children. First, she looks for envelopes and buys the large size. Second, she wants a small pad of writing paper, but she takes a large one because the shop doesn't have small pads. Third, she gets a bottle of glue. She also wants a large box of chalk, but she does not buy a small box. In the end, the shop assistant says, "What else do you want?" Mrs. Sawyer smiles and says, "I want my change!" It is a very successful shopping trip.
