answer:I think you should express your “best wishes” for a happy, long engagement. If the girl asks for your advice, specifically, lay it on her. Not so much discouraging her engagement as encouraging her personal achievement and goals. And don’t be surprised if it all goes right over her head. I have a 24 year old brother that thinks he’s going to be a famous scriptwriter because he’s attending a school that teaches scriptwriting. No matter how many times I try to drill it into his head that for the sake of his child he needs a Plan B, because there are a billion writers in the world (and gods, all of them are better than him. Ugh.) and there’s no guarantee that his scripts will pay the bills. It’s frustrating, but you can’t live their lives for them, y’know?
