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: We used to call my great aunt Nancy.  She used to be Nanny, but she gave that spelling up when she got married. 
 Response 1: Did they just confess to hearing us? Maybe everyone's finally being honest. Maybe that's what this room needs, Dean. 
 Response 2: Oh, that's understandable.  A lot of people are doing that now.  It's the newest trend.
