System: I can absolutely help! Do you have a specific day and arrival/departure time?
User: The train should leave on Sunday  and should arrive by 16:45
System: I have a train arriving at 08:09 that leaves at 07:19?
User: No, I'm sorry, that's much too early. Could you find one closer to 16:00 or 16:20?

User Emotion: Dissatisfied, disliking

Standard Response: The latest train departs at 15:48. Does that work for you?

CHange the tone of the standard response to empathatic: First repeat the request word for word without change, then give your answer (1. do not say any words or characters before repeating the request; 2. the request you need to repeat does not include this sentence).
