Both my kids are like this when I recommend things to them, it's so annoying!
DD resisted Harry Potter for years, refusing to read it or have it read to her. Then she started when it was the only kids' book available in a holiday rental and was immediately obsessed 😁
DS was exactly the same with Hitchhiker's Guide To The Galaxy until I think I actually bribed him to try it. I barely saw him that day and the next day he sheepishly requested the rest of the series.
I managed to get both to watch Firefly by mandating it as a Family Watch and they grudgingly admitted it was good.
Sadly, very sadly, I went too soon with Buffy and got DD to watch when she was 12. A good age for some kids, but she's quite sensitive and found it scary so was put off, although she did laugh a lot.
Neither will read Good Omens, despite loving the TV version 😭
Lastly, I love the Buffy attractiveness of men chart posted above, how true is that?! 😍 Giles
