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: I've been waiting for this train for a while.

SOLUTION: Me too. Feels like I've been waiting for a lot of things for a while. Like, there's this package that seems to be taking longer to be delivered than I was told.

PROBLEM: I'm sorry, please excuse me. My phone's going off.

SOLUTION: Your ring tone is somebody whispering "you're going to die?" Can you turn that on vibrate?

PROBLEM: Wait a minute, this used to be a library.

SOLUTION:
It did. It used to be a library, but no more. It was my favorite place to be in this town.
