I think you both 'handled' it just fine?
I recently was introduced to an important work client in a casual setting. In the course of our getting-to-know-you discussion, she mentioned having a stepdaughter and indicated that she was married. I later asked about her husband, and she politely corrected me—she has a wife. She wasn’t at all offended. But it left me wondering if I had been rude in assuming she was married to a man, and if, in this day and age, you just shouldn’t make that assumption. On the other hand, I can see a heterosexual person being potentially offended that I think they may be gay by asking upfront if their spouse was a man or a woman. How should I have handled this?
