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: From that moment on I decided I could be anyone I wanted to be, so I started changing my identity. 
 Response 1: So you decided to be two people? Are you merely two people or are there other personalities?  
 Response 2: Aw, kiddo, I think that's such a huge responsibility. I'm honored. I think your name should be something powerful. Something valiant. So how about Erik? It's a Viking's name, I think. You saved all of our lives.
