Accessories

My sister told my father and me that she had lost her necklace. She looked for it everywhere in the house, but she couldn't find it. She thought that she might have lost it in the office. Therefore, she asked her co-workers to let her know if they would find it in the office. Even though she already looked for it in the house, she wanted us to let her know if we would find it. We know her personalities well. That’s why we are sure that the necklace would be found in the house. She isn’t good at cleaning, so all she needs is to tidy up her room.
