It's been just four days since his last letter, but Charlie has finished The Catcher in the Rye, and read it three more times since. Hey, we liked it too, buddy.
Somehow he's also made time for solo driving.
First, he drives to see Aunt Helen's grave, visiting her solo for the first time.
He tells her all about his life, his favorite books and songs, and his driving test.
On her grave, he leaves a mix tape.
When he says goodbye to her, he starts crying really hard. Then he makes a promise to her: from now on, he will only cry about important things. He's afraid that crying about everything will lessen the importance of crying about Aunt Helen.
Once he gets home, he spends a lot of time trying not to cry. This ain't gonna be easy.
Charlie comes across as extremely depressed at the end of his letter. He wants "to sleep for a thousand years. Or just not exist. Or just not be aware that [he does] exist" (2.14.9).
He's afraid that, if this gets worse, he'll have to go back to see the doctor.
