Do you ever post an answer to a question knowing full well that the OP will not take the advice?

Sometimes I post answers, that I think are correct (to the best of my knowledge and experience) or at least try to give answers that are useful and helpful, and I truly do attempt to answer the question that was asked, but I sometimes know think that the OP will not accept the answer, for a whole host of reasons.

Why? Because when I answer a Q, I try to do so in good faith, and I often hope that the OP will eventually consider the answer that I have given, rather than just blowing it off. I also hope that in the future, if someone else, other than the OP, needs an answer to the same or a similar question, that the answer will still be valid, and might be more useful to someone else, rather than the original OP.

What about you? Do you bother answering Q’s in which you are pretty certain that the OP will not take the advice/answer?
