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: Mrs. Applebaum? Do you have the flask on you that you have in your classroom? 
 Response 1: Well, I mean, of course. I keep it in my stocking, at the very top of my thigh, so it's always warm. But I can't give it to you. You haven't officially walked yet. That would be bad. 
 Response 2: We're different guys than we were yesterday.
