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: Thank you very much.  Oh, I'm sorry, but is this proper milk?  Or is it Lactaid?  Because I have a problem with my digestive system.? 
 Response 1: That's right, and you'll be happy with whatever I call you, uh, Brad. 
 Response 2: Of course, it's Lactaid.  We're on a super yacht.
