Dear Dumb Diary: Live each day to the Dumbest

Synopsis

After a more traditional instalment as to Jamie Kelly's thoughts, Jamie stops writing for a while, having learned that her grandmother has died, which she clarifies immediately after resuming writing in her diary. After the funeral, she gets barraged with other students apologizing for her "loss", much to Jamie's confusion and distain. While looking through her grandmother's old belongings, she comes across what seems to be her grandmother's old diary. Reading it, she discovers that the writer of the diary has a crush on "M.B.", but views "A.S." as a rival to getting "M.B." Jamie Kelly starts to have a distain towards her fellow students, making passive-aggressive comments at Angeline and Hudson Rivers. When Aunt Carol comes over to see if Jamie has read the diary, Jamie learns that the diary actually was her grandfather's, and that "M.B." referred to Jamie's grandmother, whose name was "Mary Beth". The lack of drawings in the diary should have been a dead giveaway. Jamie looks back on the diary and realizes she forgot to ask Hudson to the dance. She quickly goes to ask Hudson out and Hudson says "yes." Later, Jamie learns that "A.S." is Algernon Smith, i.e. her teacher Mr. Smith. Jamie goes to the dance and has fun.
