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: It's also day into night, you know what I mean? You could be running errands and looking chic and then you go to a fancy opening or whatever. 
 Response 1: Good point, Rob. 
 Response 2: So, that's why our pets are doing all this. You've conditioned them to look admirably upon these things.
