  #Person2#: That would be great. I am really in the mood for a spicy hotpot. Any special reason for the invitation?
  #Person1#: 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.
  #Person2#: It was my pleasure. How about this evening? I feel very hungry now.
  #Person1#: Fine, I know a good hotpot place in the downtown area, food there is pretty spicy too. Shall we try that one?
  #Person2#: Ok with me. You are the boss. I will meet you downstairs after work.
