Using a suggestion from Erin today:
When growing up did your family share your love of books? If so, did one person get you into reading? And, do you have any family-oriented memories with books and reading? (Family trips to bookstore, reading the same book as a sibling or parent, etc.)
I learned to read in kindergarten. We were living in Germany at the time, and I attended an international school. I also vaguely remember doing some at-home activities to prepare me for first grade in the US. I ended up being ahead of my first-grade classmates and, rather than participating in a reading group, I was assigned independent work. I was actually embarrassed at being singled out this way (I felt different enough just being the new kid ...).
My mother was a voracious reader when I was growing up. She had "her chair" in our living room, with books piled around it and reading glasses always close at hand. (Hmm ... a bit like a spot in my family room today!) She always had a book going, and so did I. I loved the library, and as a teenager was allowed to ride my bike there on my own. This was in the 1970s (egads, I'm old), and the "young adult" genre was not what it is today. But in our library system, I qualified for a "special" library card that allowed me to check out certain books from the general fiction shelves (presumably screened for content, like a PG-13 movie!)
For many years, conversations with my mother always worked around to "so, what are you reading?" Now she's much more into quilting than books, but the internet and my own daughters provide plenty of literary conversation!
