I think it has everything to do with the OP. The OP is asking if anyone is embarrassed with what their spouse does for work, right? By definition, the only reason you'd be embarrassed of what your spouse does for work is based on the opinions of other people or "society." In my thread, not to self-promote, but I talked about just that thing. I could never see myself asking out someone who was a blue-collar worker, such as a secretary or a waitress or a cleaning lady. She may be the nicest person in the world and she may be perfect for me and you'd be right in saying "well, guess you'll never know." But that's life. You wouldn't ask out a garbage man and please don't pretend you would like "I might, I just haven't yet." No, the fact is that you wouldn't. We all sort of self-segregate and date and marry within our socioeconomic circles, in most cases. It's just a fact of life, not that we're all "bad" people. I met a girl the other night who was OK looking, but she works as some sort of a controller at a rail yard. All she talked about were trains and how much they could push. She was a very nice person, but I can't imagine having to sit and listen to her stories about train engines for the rest of my life. Nor could I imagine introducing her as my wife, the woman who works at the rail yard, unless she was totally hot.
Put it this way: what if your husband was an idiot? What if your husband was a construction worker and he had average or slightly-below average intelligence, but was a really nice guy who just happened to hit it off with you and you met when you were in college? I'm sure you'll say you wouldn't care, but lots of women would, in terms of introducing them as their husband. Like, "hi, I'm a medical oncologist and this is my husband, Bill." And then Bill says something like "yo, guys, who wants a brewski?" That's fine for when you're in medical school, maybe, but it would get uncomfortable when you're age 50 and he's still going "yo, Adriaaaaaaaan!!" It's no different.
