LOL! I may be a shallow know it all, it's possible.
But I am a very safety conscious shallow know it all, who has 40 plus years of horse knowledge and experience, most of which involve handling stallions. First for my parents breeding operation and now for my own operations. I, indeed, married a man (I'm not a sir btw) who knew nothing about horses, and even after 22 years of mostly happy marriage catch myself thinking, "Why the H*LL did I marry a non-horseman? Life would be so much easier if......"
If you truly do know people who have non-horsemen in their lives, then you probably also know that there's no way in the world that they would allow this non-horseman to make decisions/dictate policy about how the horses are cared for, what kind of training/treatment they'd receive or whether or not a horse should be gelded. I don't and have never consulted with my husband on anything pertaining to horses, except whether or not the budget would stand for me to add another one. He doesn't consult with me about his medical practice, so we're even.
We have a standing joke around here when he tries to overstep his bounds into my business. I hold up a pair of my shorts and ask him, "Who wears these pants? Can you get into them?" In the beginning he fell for it and said, "Well, they're your pants, no I can't get into those, they're way too small.". I replied, "Well sir, if you don't change your attitude, they'll remain too small and you'll never get into them.". He got the hint.
