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: It's the first week of spring and so much dander in the air. Isn't it everywhere? 
 Response 1: There's just so much dander. It's like you can cut it with a knife. 
 Response 2: Look, you and your brother are kind creeping everybody out. You got these weird looks on your faces. You're throwing ice cream on the ground and you're saying "it wasn't us who did it." You're blaming somebody that nobody can see.
