Having returned from her round trip (往返旅程), the angry woman stood outside the ticket office of the station. “The railway owes (应给予) me£12,” she said to Harry Jenks, the young man working at the office, “you sold me a ticket for May 22nd, but there was no ship from Jersey that night. So my daughter and I had to stay in a hotel. It cost me £12.”

Harry was worried. He remembered selling the woman a return ticket. “Come into the office, madam,” he said politely, “I’ll just check the Jersey timetable for May 22nd.”

The woman and her little girl followed him inside. She was quite right, as Harry soon discovered. There was no sailing on May 22nd. How could he have made such a careless mistake? He shouldn’t have sold her a ticket for that day. Wondering what to do, he smiled at the child. “You look sunburnt,” he said to her. “Did you have a nice holiday in Jersey?”

“Yes,” She answered, shyly. “The beach was lovely. And I can swim too!”

“That’s fine,” said Harry. “My little girl can’t swim a bit yet. Of course, she’s only three…”

“I’m four,” the child said proudly. “I’ll be four and a half.” Harry turned to the mother. “I remember your ticket, madam,” he said. “But you didn’t get one for your daughter, did you?”

“Err, well…” the woman looked at the child. “I mean… she hasn’t started school yet. She’s only four.”

“A four-year-old child must have a ticket, madam. A child’s return ticket to Jersey costs… let me see…£13.50. So if the railway pays your hotel, you will owe £1.50. The law is the law, but since the fault was mine…”

The woman stood up, took the child’s hand and left the office.
