Dunno, but I always wondered about the really outrageous and public proposals, since it seems like the girl pretty much has no way to say no.
But then again, I imagine that the idea is to hit them at the most romantic moment (point of greatest yestitude), which will probably not be the same point at which you’ve returned from a romantic night out, tired and wanting to go to sleep.
I think it’s just a nice tradition that makes things “official.” I suspect that most people are already “unofficially” engaged prior to the big moment–meaning, they may have even talked about marriage, when they’d get engaged, living together, whatever. IOW, by the time someone asks, it’s largely a foregone conclusion. Just my opinion, of course.
I think Stratocaster has it. “Popping” the question is just a way to make the moment memorable. (As opposed to the ancient joke in Playboy, “How’d you like to do this every night?”)
I proposed at dinner while taking Deb out for her birthday (no joining the crowds of proposers on Christmas Eve, for me) because it made a romantic moment more memorable.
I can’t even imagine proposing to someone if the answer was in doubt. (I know that folks do; it just strikes me as odd. I think my Mom declined my Dad four or five times. However, they each knew that they were going to marry and she was just putting off the specific commitment until their end-of-depression economic situation was more secure.)
I agree that in most cases it is pretty much a done deal, but not always. When I proposed we hadn’t even seen each other for over a year, me being in Illinois and she being in New Hampshire and then Philadelphia. However, in a rare burst of cluefulness I had gotten the impression that she was interested, and would say yes when she came to help me move. I was right, though she claims to have not actively considered the possibility.
But I sure as hell wouldn’t have wanted to pop the question in a crowded place.
