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: Is that your writer friend with my wife down there in the parking lot? 
 Response 1: Is that what this is? 
 Response 2: I don't know I've just been watching what's happening, not who the people are. I find that's easier and when I'm doing my little covert tryst watching.

Response 2
