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: Well, I suspected the post office came to life after hours.

SOLUTION: We all did. I mean, they're losing stuff all the time. I had so many birthday cards get lost on the way to my house, I just figured they got up and ran away. That's the only logical solution.

PROBLEM: I love this library and I hope it never goes anywhere.

SOLUTION:
It's amazing and it just makes this place feel like a small town. I feel like it's our kind of people.
