Boys do not keep a personal diary. Or lead? Greg Haffley is in school and his life is not easy. They call to the board exactly on the day when he... well, I didn't finish something there. And at recess and after school, he is surrounded by tall, scary, angry high school students. The girls giggle over him and even notice a tiny pimple jumping up behind his ear. No one understands how hard Greg's life is: neither his parents nor close friends.
