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 met anyone else? I didn't think there was anyone else in this maze. 
 Response 1: Yeah, they're very forgettable though. I don't remember a lot of their names. 
 Response 2: Oh, nothing, father. I just wanted to make sure you and I would still have plenty of "us" time, what with these new friends joining us and so forth.

Response 1
