For one of my classes, I have to read the middle grade chapter book, Flora and Ulysses.  Four of the five main characters are either writers or are inclined to writing tendencies.  This fact reminded me about something I read in a book about introverts.  Books are often written by introverts because they tend to enjoy things like sitting still, pondering, and etc. that are inherent in writing.  Also, there are some introverts who wish they weren't introverted but the fear of being social is so great that it overpowers their desire to engage in social situations.  Books, like other media, provide shy authors a way for them to become involved in situations that their shyness prevents them from engaging in.  Because of that, book characters themselves often demonstrate introvert characteristics.

Since authors generally write about characters similar to themselves, whether they portray them as writers or as introverts, it is interesting to think about how people who are like the authors will generally be the ones who like to read.  Perhaps a love of reading doesn't stem from actually enjoying the reading process, but more from characteristics that the writer and the reader have in common.
