TASK DEFINITION: Given the sentence, generate "yes, and" response. "Yes, and" is a rule-of-thumb in improvisational comedy that suggests that a participant in a dialogue should accept what another participant has stated ("Yes") and then expand on that line of thought or context ("and..."). 1 In short, a "Yes, and" is a dialogue exchange in which a speaker responds by adding new information on top of the information/setting that was constructed by another speaker. Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange, although it could be the case if it agrees with the description above. There are many ways in which a response could implicitly/explicitly agree to the prompt without specifically saying 'yes, and...'.

PROBLEM: You like concerts in general, but mainly Phish concerts, right?

SOLUTION:
I mean, Phish has like, become a lifestyle for me. But I do go to a lot of other concerts. Sometimes I wonder if Phish knew I was going to a bunch of other concerts, and not exclusively Phish concerts, would they get jealous?
