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: Oh, look at that. He flew away. 
 Response 1: I completely understand, Dr. Lecter. I will not fight you. 
 Response 2: Yeah, he has these wings. It's an invention. They actually fly. He thought he was gonna kind of retire on that, but no one wanted actual bird wings that they had to attach on to themselves. It's kind of an invasive surgery.
