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: Mary Sue, you're wearing that same hanker-chief shirt you were wearing when I met you. Charming, I'm sure. 
 Response 1: She's finally grown into her hanker-chief shirt that she's worn for years. She was horrifically underdeveloped for quite a long time. 
 Response 2: We share the same mind. I mean, in a marital sense. Of course.
