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: Have you seen me before? Have I been on this plane for awhile? 
 Response 1: My goodness. You've been here since the beginning. Do you not remember? 
 Response 2: Oh, you mean like a genius playlist where you start with Walking on Sunshine and then whatever.  It'll see if you like that or you could say it's all K and the Waves.
