Guest post by "Whirlwitch" I believed that cork trees grew exactly like they're drawn in The Story of Ferdinand - trees with little wine corks growing as fruit. It took a long time before I learned what cork was, and realized that that illustration was a joke.
I also believed that boys and men had short hair because they couldn't grow it long - the first time I saw a man with a long ponytail I was amazed at seeing an impossible thing. Then I wondered why, if boys could grow their hair long, did at least some of them not do it?
