For me, that’s people who mean well but who keep making unrealistic suggestions that are based on wishful thinking.
Such remarks can come from people who are living privileged lives but aren’t aware of it. Their helpful suggestions usually only make you feel powerless and can drain your energy because there’s no point in saying anything about it. They wouldn’t get it.
If these are also often people who make odd, sneakily undermining negative remarks about your character, your confidence or your abilities, you have to wonder what is really going on. You have to avoid those people or at least limit (manage) your exposure to them.
The good thing? If you have lived long enough, you will be able to spot such patterns.
