I Hear My Boss's Secret Crush

At the Company Annual Gala, I won a prize: taking my boss home for the Lunar New Year. The man looked cold and said if I was unsatisfied, I could choose Cash Redemption instead. I was just about to agree, when I heard his inner voice: I'm so excited and happy, my wife is taking me to Meet Partner's Parents! What should I wear that day? Never mind, I will wear the same color as my wife. Would it be impolite to call them mom and dad at the first meeting?
