One Friday night, Emil hung out with his friends in a bar, where they drank, ate and talked. They didn’t feel like going until one of they became too tipsy to move. It was already really late at night, or rather, early in the morning. The only public transportation was the taxi. Emil supported the drunk guy and waved to a coming taxi. He was going to bring his friend home. In the taxi, Emil and the driver had a small conversation:

A: Do you usually walk home?
B: yes, it doesn’t take so much time.
A: But I also take subways, there are 5 stops.
B: Oh, I see.
A: How long have you been learning Chinese?
B: About two years.
A: Do you drive?
B: No, it is hard to find place for parking.
