   neutral   I am thinking about inviting you to a dinner. When would you have time? And what kind of food do you fancy?     neutral   That would be great. I am really in the mood for a spicy hotpot. Any special reason for the invitation?  
    neutral   To thank you for helping me at work last week. If you would not have been so kind, I would not have been able to pick my parents from the airport. You really did me a big favor. Thank you so much.     neutral   It was my pleasure. How about this evening? I feel very hungry now.  
    neutral   Fine, I know a good hotpot place in the downtown area, food there is pretty spicy too. Shall we try that one?     neutral

 Good. Is it far? We can walk or take bus 316. Which season are
