Teacher: If the emotion of happiness is present in the one of the dialogues of the conversation, then output Yes otherwise output No
Teacher: Now, understand the problem? If you are still confused, see the following example:
So Dick , how about getting some coffee for tonight ? Coffee ? I don ' t honestly like that kind of stuff . Come on , you can at least try a little , besides your cigarette . What ' s wrong with that ? Cigarette is the thing I go crazy for . Not for me , Dick .
Solution: Yes
Reason: Here the first sentence indicates the soft tone and how exciting the speaker is for drinking coffee and it suggests overall happy tone and the output is yes. So this is a positive example.

Now, solve this instance: Good evening , madam . May I help you ? I want a facial . But this is the first time I've come here , so can you tell me how you do it ? Sure . Most facials start with a thorough cleaning . Then we usually use a toner to invigorate the skin , followed by exfoliation treatment-a peeling mask or scrub that removes the dead cells that make the skin lock dull . After that , we'll massage your face and neck with oil or cream to improve the circulation and relieve the tension , followed by a mask to moisturize and soften the skin . That's exactly what I want . How long does it take ? We have half-hour and one-hour treatments . What's the regular price ? Well , the half-hour facial costs 50 yuan and the one-hour costs 80 yuan . If you want make-up , another 20 yuan will do . Good , I will take the one hour facial with make-up . That's fine , madam . By the way , could you give me a manicure ? Use a light nail-polish , please . Yes , madam .
