I'm an avid reader & always have been, I know I could read before I went to school, my mum taught me. She used to read a lot when she was young, as did my dad but, I cannot remember her doing much in her later years. We always had lots of books & dad bought us a set of Encyclopaedia Brittannica when we were growing up, they were really expensive back then.
Mum's dad also loved to read, he used to buy me books for birthday & christmas, I still have the Peter Pan, & the Wind in the Willows, Tom Sawyer, Huckleberry Finn, Beau Geste, & Just So Stories, The Children of the New Forest fell apart because I read it so many times.
My middle sister never reads other than cookbooks, or occasionally reference ones about dogs or horses. She is dyslexic, which wasn't recognised back when we went to school. Her son loves to read.
My youngest sister is another avid reader (as is her husband), her eldest three children, always have been, her youngest is severely dyslexic but over the last few years has discovered Robin Hobb, Margaret Weis & Tracy Hickman, & is as hooked on reading as the rest of us.
So did we inherit our love of reading, or did we learn to love reading through education &/or our environment?
