When I lived with my parents, there was both my mother & myself who weer heavily into bokos. She benig older & having her own money would buy most of the books, though I was able to read them too. As I got older, our tastes began to differ wildly - she likes Catherine Cookson, whereas I always hated those books, & I loved Terry Pratchett whereas she can't get her head round the fact that ther are no chapters. We both always loved a good horror though.
Now, there's just me & my hubby at home & he doesn't read at all. I try to encourage him (he expresed an interest in having the Lord of the Rings trilogy as he read them when he was a kid, but they've lain, untouched, ever since I brought them home - I don't like Tolkien, you see). Every other book in our flat is mine & there are literally thousands of them:
I have a six foot tall by four foot wide bookcase as well as a 4 foot high by 3 foot wide bookcase crammed with books. I also have 6 large boxes in my spare room cupboard. There aer also at least a dozen more boxes of a similar size in my dad's loft. To finish off, i have a small set of 3 shelves under my computer desk which houses my "to be read" books. All newly aquired boks get put here till I manage to read them, then they get moved to the other shelves.
It's a whole lotta reading, but someone's gotta do it - LOL!
