At the new year day, Lily's grandparents came to see her from the countryside. They lived at there for a long time. On the way home, Lily introduced some changes about the city to them.
Lily=L Grandpa & Grandma = G
L: Happy New Year, grandpa and grandma. Long time to see you.
G: The same to you, Lily.
Lily helped them to pick up some luggage and brought them to the bus station.
G: What a big station here! There weren't any stations here. When we wanted to go some places, we only walked to there or by a track.
L: By a track?
G: Yes, some track used to carry pigs, stones or rubbish.
L: Oh, that is surprise to me.
Five minutes later, they arrived at Lily's home.
L: Please get up. It's here.
G: Woo, it's so fast now. At that time, we spend 40 minutes to arrive here. But now, we only spend 5 minutes. The city is quite different.
