I also have a whole spiel for them about not buying novels for their lit course reading list on Amazon, because if they go to an actual bookshop not only will they be supporting staff with pleasant working conditions but they might also see another book on the shelf they fancy reading.
I know it would be off to Social Services in 2020, but in 1970, when my DM went shopping, she parked me in the library (for some reason the kids section was upstairs. Which seemed stupid at the time, although in hindsight, I get it ...) and went about her shopping.
Apparently it was the one place you could leave me, and find me when you went back
.
So growing up, sport-infested TV was never a problem - I'd pop to the libraries nearby and trawl the shelves. Hopefully DS picked a bit of that up. At least he isn't afraid of books.
Of course the flipside is you can wander into some very dark places without much protection. DM liked Dennis Wheatley and that pulled into some pretty gruesome horror anthologies on the shelves ... The Pan series, edited by Herbert van Thal being seared into my mind.
(Just as an illustration of my DM, I showed her one when we were in the library, and she flicked though it and said "Dulcie Gray ? She used to be on the radio ..." )
