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 think a lot of us thought you'd be saying the same vows to each other at the same time, not separate things at the same time. 
 Response 1: Oh, did we not? I thought we were. I couldn't hear because I was saying my own vows. 
 Response 2: Don't worry about it, the elevator will be back up shortly. There's an electrical problem with the light. Maybe it's alternating current or direct current.

Response 1
