Roald Dahl's Inspiration

This summer I read a book called "Matilda" by Roald Dahl. It is about a girl named Matilda having a knowledge of an adult in an age of a toddler with phenomenal reading skills. But her talent is hidden with her awful parents that are completely bias towards her older brother, and a headmistress, Ms. Trunchbull, who treats students like punching bags. Before I read this book, I read an autobiography "Boy" by Roald Dahl about his childhood how he suffered from the people in his school at the 1920's and 30's time period as the character Ms. Trunchbull. Also, in Roald Dahl's autobiography, I found that he got the inspiration for "Charlie And The Chocolate Factory" from his love for chocolate in his childhood. It is great for writers to use memories from your past to create stories!
