When I was 3 I used to ask all grown ups why it was they could read and I could not. My granny answered that was she had learned how to do it. That earned her the job to teach me.
When I was four they made me read the newspaper for entertainment because I used to read the text I did not understand with a very funny expression.
I also had a habit to read to all the children in the neighborhood aloud. As no one else was able to read they said I would make up the stories and when I answered, no, you can have a look yourself, they would always beat me up. So reading taught me fighting for myself and for knowledge
