I was doing the exercise that teacher had given us earlier. When Sarah arrived at the party, Paul had already gone home. The house was dirty because they hadn't cleaned it for a long time. She had just got home when i phoned. Sue had already had breakfast. Sam had never played tennis before. I hadn't seen them for five years. He was nervous because he had never flown before. I thought i had made a big mistake. I remembered that i had left my keyes home.
