I was thinking about this thread today talking with a friend about her husband. He often has to learn things by experience, rather than being told. For example, they went out to a "fancy" restaurant she really likes, and he was determined to order something she didn't think he would like. Normally I'm not much for regulating other adults' food; but it was something like "mashed potatoes" and even though he loves regular, plain, bland mashed potatoes, she was sure this fancy place would prepare them in a fancy way, which he wouldn't be expecting and wouldn't like. She tried to explain this to him, but he insisted on getting the mashed potatoes. And didn't like them. And it was actually his entree, which was somewhat expensive, and now he doesn't like the whole restaurant and doesn't want to go there for a special occasion.
Okay, not the worst scenario in the world, but I just thought it was interesting how some people don't like to take advice even as they get older. And note that his lesson was not, "Maybe I should listen when my wife makes a suggestion," it was, "This restaurant makes food I don't like."
