I grew up without books at home, but my DM frequently read magazines.
Surprisingly, I turned out to be a big reader in adulthood. I have bookcases either side of the chimney breast filled with books (as well as LEGO sets and a couple of ornaments) I also have a bookcase on my stairs and in the office, which are filled.
Whenever I visit my DM, I’m reminded of my childhood without books and it makes me quite sad!
