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: Sorry, I just got excited. 
 Response 1: I know, it's just, you are still a stranger and we're just on a train platform. And when someone rushes at you, I've seen too many movies where someone kills someone by shoving them in front of the train. Haven't you seen that? 
 Response 2: You were the first mate. Did you get amnesia? That does happen when you get caught in the belly of a whale.
