We didn't meet Jim, we met Max. He didn't leave last Tuesday, he left last Thursday. We didn't see Jack, we saw David. They didn't buy a Volvo, they bought a Fiat. You didn't know the answer, Tom knew the answer. I didn't lose my passport, I lost my ticket. He didn't write a letter, he wrote a postcard. The film didn't begin at 6:30 p.m., it began at 7:30 p.m. My sister wasn't at the theatre yesterday, she was at disco.
