I don't have great context for how people spoke 50 years ago, but I have noticed that older people often speak in references. Like, I don't understand what you're saying because I didn't watch The Andy Griffith Show or know baseball drama from the 50s.
Where are the lines between idiom, reference, and meme?
Are we doing it less, or just replacing them with new ones that older people don't recognize? (I do think we are doing it less in spoken word, but more online)
