Three pigs

I find the book “three pigs” is more proper for adults to read than children. I never see a wolf when I was a kid, so I didn’t know how horrible it was. Actually, I felt that the pictures of the wolf in my book were cuter than that of three pigs. However, I reread the story today, and I feel profound scary because I understand that the relationship between three pigs and wolfs is like that of the malicious people and weak ones. Just like the three pigs, I am also afraid that someone keeps chasing me and wants to kill me. Children can not understand this, don’t them?
