Diary Of A Private School Kid by Penn Brooks is a burst of humor for the weekend. There is a lot of humor that leaves me with only one question. Was this written by a really cool kid developing writing skills or was this written by an adult (whatever that means)? The Amazon Author page reveals that Penn Brooks lives with his wife and four children, so another possibility is that he is channeling one or more of his children. Brooks reveals that he likes writing for children and adults who never grew up.
