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: That guy is my nemesis. We went to middle school together and he just loves throwing parties and having people over to his house, the McCormick place. Maybe you've heard of it? 
 Response 1: I have, but what's funny is that he's very shy. 
 Response 2: This is so exciting. I can't believe our story was made into a major motion picture.
