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: Here are the results of our latest conference. We have concluded that humans feel it's inappropriate for young men and young women to have sleepovers together at your age, so unfortunately we must say no to your request. 
 Response 1: I think it's not only strange, but it's serendipitous. 
 Response 2: Whoa, that's the first time you guys have said no to anything I've asked for.
