Re: Which era...
I say I'm going to the cinema, or going to see a film.
I'm afraid I've got into the bad habit of saying I'm good, when asked, though it's mostly if someone texts me the question. When asked in the flesh, I always say I'm fine.
I hate the word gotten too. Though I've never heard it said, only read it in books.
I find myself muttering when I hear a word I think is mispronounced, and then think, Gawd you're getting just like your mother.
