Sally Brown’s best-known Peanuts line is a cheerful pitch for reading from a character who usually wants nothing to do with school. “Happiness is your own library card” appeared on April 26, 1963, and remains one of her most memorable lines.

3. Conjugate your verbs
Sally is Peanuts’ patron saint of unwilling students. Most of the gang don’t seem to mind their studies. Patty isn’t good at school, but she doesn’t resent it as actively as Sally does. For kids trying to wriggle out from under public schooling, Sally is their representative in the strip.
Her resistance to school doesn’t mean she’s against learning, though. Like Linus, she can suddenly produce graduate-level Biblical scholarship. That contrast makes her library-card line all the more striking: Sally may dislike school, but she can still make a persuasive case for reading.
2. Your own library card
“Happiness is your own library card,” from April 26, 1963, is one of Sally’s best-known lines. It’s a natural fit for school walls and literacy drives, and you could reasonably call it her most quotable line in the strip. Its cheerful simplicity also contrasts with Sally’s usual frustration with school.
Another Sally strip offers a different kind of advice, this time about handling conversations online.
1. Come correct or not at all
Sally is one of comics’ great poor students. Throughout the strip, she tries to escape schoolwork with bluffs, short cons, and turns of phrase, though she’s never as sharp as someone like Calvin.
In the strip dated June 11, 1987, Sally starts a letter with “Deer.” Charlie Brown tries to correct her, but she carries on by writing what looks like the opening of a term paper about deer. As Charlie Brown retreats, she yells: “It seems to me that a lot of the problems in this world are caused by people who criticize other people before they know what they’re talking about!”
Once Charlie Brown is gone, Sally starts over and writes “Dear Grandma,” just as he suggested. The joke makes a useful point: people can cause problems by criticizing others before they understand what they’re talking about.
That lesson fits social media, where it’s easy to jump into an incomplete conversation without knowing the full context. Sally gets the spelling wrong, but her advice still holds: lurk more before posting. The nearly 50-year-old strip offers a simple way to avoid screwing up on Bluesky.
