Поставить глаголы в скобках в правильное время.

Dana Miller was a bus driver in the city of Philadelphia. Her working hours __________________(BE) from 10.00 pm till 6:00 am. It was a hard job and very few __________________(WOMAN) worked as bus drivers in those days but Dana loved her job very much. One of her regular passengers was a guitar player. Every Friday night he got on the bus carrying his guitar. The guitar __________________(MAKE) of wood, not plastic and Dana liked the way it sounded. “You should come to see our show,” the guitarist kept saying to Dana.
“I __________________(SEE) it one day,” Dana promised each time, but she never said when exactly she __________________(GO). Another passenger who often used Dana’s bus was a Biscuit Lady. She worked at the biscuit factory and often __________________(GIVE) Dana a small bag of biscuits. Dana __________________(NOT/LIKE) sweets and pastries very much but she could never resist those biscuits — they were so fresh and tasty. “How was your night?” Dana’s husband liked to ask __________________(SHE) when she came home.
“Good music, good food and a great view of the city,” she cheerfully answered. “I wish I __________________(ENJOY) my work as much as you enjoy yours,” her husband said, “ but I’m going to have just another boring day at the office.”
