单选题
Mrs. Baker's sister was ill. She had someone to look after her from Monday to Friday, but not at the weekend, so every Friday evening Mrs. Baker had to spend the weekend with her sister at her sister's home in a neighboring town. But as Mr. Baker could not cook, so he had arranged for(安排) his sister to come over and spend the weekend looking after him at their home.
This means that Mr. Baker had quite a busy time when he came home from work on Friday evenings. First he had to drive home from the railway station. Then he had to drive his wife to the station to catch her train. And then he had to wait until his sister's train arrived, so as to take her to his house.
Of course, on Sunday evenings he had to drive his sister to the station to catch her train back home, and then wait for his wife's train, so as to bring her home.
One Sunday evening he had seen his sister off on her train and was waiting for his wife's arrival, when a porter, who had often seen him at the station, came over and spoke to him.
"You are having a lot of fun, " he said. "But one day one of those women is going to catch you with the other, and then you will be in real trouble!"
