I was reading adult books by grade 4. We would go to the library every 2 weeks, but I could only check out age-appropriate books under the library's rules. I would have all 7 books read by that night. I was and am a voracious reader. I loved going to New Orleans once or twice a year because my aunt was a voracious reader too and for that week I could read all her books (A. J. Cronin, Frances Parkinson Keys, James Fenimore Cooper, Thomas B. Costain; Look, Life, and Readers Digest magazines). I guess my parents wanted me to have a balance to my life. At least candy was my second choice.
I usually have between 5 to 8 books going at once, in various places in the house and car.
