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: I just love that you're so tough. And now I want to make you my maid of honor. 
 Response 1: I'm absolutely in. Thank you so much. I don't have any friends so this is like a dream come true. 
 Response 2: Yeah, it was like a human heart attack; they were jamming up the bloodwork of the weigh-in.  It turned into a free-for-all.
