Not Christmas but for my 40th a friend gave me some books that were part of a series and said ”They’re good, I’ve read them.”
Turns out that not only had she read those actual ones, and turned over the pages to mark them, but she enjoyed books 1 and 4 so much, she kept them and gave me 2, 3 and 5 from the series.
It’s probably not the point, but she gave up work at 37 because she inherited a massive pile of cash and now describes herself as a “professional potterer” - as in someone who potters about.
So she possibly could have stung for new copies....
