I chose this topic because we question when we read news, articles, and almost all the information we receive now, but tended to believe everything in the books when we were children. It is easier to correct the knowledge I gained from children’s books. For example, I read in a book that there were nine planets in the solar system when I was in kindergarten, but now there are eight. I can easily update this in my mind. But some other more implicit ideas that I generally internalized as a child without recognizing persisted even after I grew up and learned to question. I read several of my favorite books in childhood again. Now I see many descriptions in the books obvious gender stereotypes, but for a long time, I thought perfect girls should be elegant and quiet. And even if I already found it ridiculous, largely because the notion of society changed, I still occasionally judged myself in this way unconsciously. I feel complicated as those books sparked my love for reading, but they also composed the prejudice I have. Because they were connected with the carefree memories of childhood, I was consumed with a nostalgic mood which took me a longer time than I expected to admit.
