I know this much...Miška would have killed me if I popped the question in public.
I've seen a couple of these high-profile proposals explode in the man's face before...almost like it's a ratings thing. At first, everyone wanted to see "the guy declaring his undying love in front of everyone", then they wanted to see the trainwreck of him being completely pw3nd before the world.
I hate to wax romantic, but it seems like the whole thing is about the spectacle, not the true moment at that point and really, what marriage would last based on something that superficial?
