I'm famous," writes Greg, "I'll have better things to do than answer people's stupid questions all day." So was born the Wimpy Kid's diary. Written by
Greg Heffley decides to keep a journal, not only because his mother wants him to, but also because he wants something he can give to people who ask him questions once he is rich and famous. In handwritten type and through the use of cartoon illustrations, Greg details his day-to-day life as a middle school student and gives his opinion on bullying, why girls like boys, where to sit on the first day of class, how to draw cartoons and numerous other topics, such as the cheese touch.
The cheese touch is a middle school ailment similar to cooties that comes from touching an old piece of cheese that rests beneath the basketball hoop on his school's playground. If you touch it, you have the cheese touch until you touch someone else. Then they have it.
At home, Greg is a middle child. Greg's older brother, Rodrick, plays practical jokes on him; Greg thinks his younger brother, Manny, is spoiled. He believes that his parents don't understand him. They do unforgivable things, such as telling him to stop playing video games and go outside. When that happens, Greg goes to someone else's house and plays video games.
Greg's best friend is Rowley. They became friends because Greg felt sorry for Rowley. All the mean things that Rodrick does to Greg, Greg does to Rowley, along with a few ideas of his own. One day, Greg goes too far and lets Rowley take the blame for chasing kindergartners all the way home, instead of walking them home, as a Safety Patrol person should. As a result, Rowley stops hanging out with him. Greg does not understand why. But later, when his classmates ask how the cheese under the basketball hoop disappeared and Greg knows that a group of older bullies made Rowley eat it, he tells his classmates that he (Greg) threw the cheese away. Although his class now flees his cheese touch, he and Rowley resume hanging out together.
