"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.

Prompt: David, I must confess. Last night, as we were slumbering on the river boat, I heard you in the cabin next door to mine. It sounded like you were waking up from a dream screaming "Ow, ow, my back hurts." 
 Response 1: That's right. I've been having those dreams every night. 
 Response 2: As a guy named Guy, I'd say let's hear them out.
Response 1
