When I was 11 or so, we got a call like this to our house phone, and I was the one that picked up.
Woman: Is your mum there?
Me: No.
Woman: Because she said she’s looking to install double glazing.
Me: No, she’s not [Because she wasn’t!]
Woman: [Pause] Oh, so I’m lying, am I? Silly boy. [Hangs up]
I’ve never recovered from that phonecall.
