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: Dad, you're just an old troll, who likes to be under the ground and dig for things. Dad, can't you see that I'm more like a bird and not the kind of bird that flies into the coal mine to die. I'm the kind of bird that wants to fly around and sing! 
 Response 1: So, who are you singing today in this here opera? 
 Response 2: Sorry, we're just indulging in a little post coital mysticism.
