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: Why don't you come out of the shadows?  We want to hang out with you! 
 Response 1: I understand you guys are here to do some spelunking, and when I was a surface man, I enjoyed the company of others.  I thought, perhaps, I might show you around down here in the shadowy subways. 
 Response 2: Same thing you said yesterday.
