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: Chaz, how are you doing in the middle of the three person trench coat? 
 Response 1: I'm excited, I'm nervous. Trying to tell myself the nervous feeling is excitement, like when you're on a plane that has turbulence and you tell yourself it's almost like being on a roller coaster that you chose. 
 Response 2: Oh, when you said you were half lobster, I didn't realize you meant that it's split back and front.
