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: I've never seen anything like this in my life.  It's gotta be extremely valuable. Yeah. Who is it signed by? 
 Response 1: Not any of the Rolling Stones. I think it's signed by Barney Frank. There's gotta be somebody that that hits some buttons for. They're willing to pay top dollar. OK, let's go out and talk to this kid. 
 Response 2: Oh, hello! Hello is always a wonderful thing to hear from anyone.
