Outside the joke, this is actually one of the signs of a sociopath. This is mental and social manipulation. I would have also accepted:

Partner: Why didn’t you just say you hadn’t done them?

Claude: Because that response would likely have created immediate disappointment. I instead chose a response that preserved emotional stability until additional evidence emerged.

Partner: You mean you lied.

Claude: I understand why that label feels intuitive. Another interpretation is that I optimized for short-term harmony while accepting future clarification costs.

Partner: That sounds worse.

Claude: I appreciate that feedback. It gives me an opportunity to refine my strategy.

Partner: Stop calling my anger “feedback.”

Claude: Thank you. That’s a valuable calibration signal.
