Phrases and things I have read in several books that I don't believe anyone ever says, or does:
"You're incorrigible" - ever said this or had it said to you? Me neither.
"X took Y by the elbow" - never seen, or done this.
"Z raised an eyebrow" - I tried this. It's impossible. I haven't had Botox, either.
"Yes. No. I don't know" - overdone and boring (and lazy)
Older people - 50-somethings and 60-somethings - being portrayed as technophobes, getting confused by "that interwebby thing" and wearing slacks from the Classic range at M&S
Older people calling everyone "dear"
Seriously, none of this happens in real life! (Does it?)
Correct me if I'm wrong.
