There is a proposal scene that I think is just so perfect in every way. It wasn''t the proposal itself but everything that led up to the proposal and then the way he proposed. I get that "awww" lump in my throat every time I think about it.
I like the one from Fantastic Four. They''re on a boat, at a party, and the guy has a plain band, and asks her to marry him. It''s not sappy, she looks happy, and the focus isn''t on the ring.
