Very interesting discussion, boomerang.
I wonder if it's a role model thing at all? That's one part I'm not sure of, how much the parents read.
Neither of my parents were readers, in fact they'd had minimal (if any) formal education at all. The was no reading matter at all in our home.
We arrived in Australia when I was one year old, as migrants/refugees.
For the first few years of our life here, we all spoke Ukrainian at home, so I couldn't speak English when I started primary school.
The thing was, from the minute I learned to read, I couldn't stop! I would almost describe it as a compulsion. I read & read & read & read! I just loved it!
My sister, who is about 6 years older than me, has shown little or no interest in reading throughout her life.
Why were we so different? I honestly don't know, though she was a lot more extroverted than me & threw herself into the social life of the community while I read (also & wrote & and drew) heaps ... at school & at home. We have very different natures.
I think, to me reading was almost a life raft, it took me completely out of the world I was living in & into other entirely different worlds ... maybe it was a form escapism? Something which completely removed me from the sometimes melancholy & difficult life we were all living through at the time?
