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: What if I say "your hair is almost the perfect length"? 
 Response 1: Well, you used the word perfect, so that's probably a bad way to go. Never use the word perfect. 
 Response 2: Those are for all the soles that got lost.

Response 1
