I've always thought public wedding proposals are lame. It's like you have to do it in front of people so it's harder to say no. Or cause you need support to do it.
This ones cute...but still, why at the movie theatre with all the friends? If it was just you two at the theatre(not an empty theatre...I just mean the two of you without a bunch of your friends around) maybe it would be okay. I know, I know....I have stupid rules for how society should work. Sorry.
