Definition: "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..."). Given a prompt and two responses, identify which response is the type of "yes, and". Indicate your answer by 'Response 1' if the first response is correct, otherwise 'Response 2'.  Note that a "Yes, and" does not require someone explicitly saying 'yes, and...' as part of a dialogue exchange.
Input: Prompt: It's all in the book. The national Iceland book that we all live by. 
 Response 1: It says that, to make the customers comfortable, you should use American southern dialect. Which is what I do. 
 Response 2: Yeah.  Yeah, it's going to be amazing.  So, people love sushi, and they love just hanging out chatting with friends.
