FFBBT613 – Sorry, but if you want their monetary support, you will have to play by their rules. Unless you were planning on paying for seminary yourself? You get to make your own decisions once you are 18, but not with their money.
Are you saying that as a practical measure, or as what you think the result should be.
I don’t think you’re correct even as a practical result. Many parents actually want what is best for their kids, and are willing to even pay money for things that their kid wants even if they personally don’t want it.
