You can lecture children on how to behave until your mouth runs dry, but the children will end up emulating your actions/behaviour because they do not seem to have a well-developed sense of understanding through hearing. This is, I believe, why my children are readers because they have grown up with parents who read a lot.
The older one is a full-blown reader at fifteen and is already flirting with philosophy books, no thanks to me because that is the father's kind of genre. She is into biographies, also no thanks to me, and even though she is my child, I find it fascinating when I listen to her discuss Rasputin and other historical figures with her father.
