In the end of the excellent 1940 movie “The Philadelphia Story”, Tracy Lord and George Kitteredge call off their wedding right before it’s supposed to start. They’re worried about how to tell the wedding guests and how they’ll react. In that context Elizabeth “Liz” Imbrie says this:
Don't get too conventional all at once, will you? There’ll be a reaction.
My question is, what does Liz mean by “don’t get too conventional”? Does she mean too old-fashioned or traditional, or what?
Is she saying “Don’t assume the guests will just politely say nothing, they will react to it?” Or is she saying “Don’t worry, they’ll just react to it and that will be it, don’t act like this sort of thing never happens.”?
