Xin Tao: Yang Yang, I've invited Ling Ling to go mountain climbing this Saturday. Are you going?
Yang Yang: I'm going! I'm going! At what time do we meet on Saturday?
X: We meet at the gate of Fragrant Mountain at 8 o'clock in the morning. Don't be like last time and break the appointment again.
Y: I failed the appointment last time because of traffic jam. This time I won't and I'll get up early for sure.
X: It's a deal. Don't leave without seeing each other.
