Fifth grader's hilarious note on her rules goes viral

We all have our boundaries -- but one little girl made sure everyone, especially a boy named Noah, knew hers.

Twitter user WhosDenverJoes posted a photo of a list of "rules and regulations" from a fifth grader named Zoë to Noah.

She obtained the photo from a friend, who is a teacher.

It's clear from the note that Noah, who is portrayed as a stick figure, has been terrorizing Zoë. She writes that Noah must not touch or speak to her, and cannot play with her on the bus.

Zoë does not hold back; she lets Noah know that she has a short temper and does not not tolerate "people like him." Noah is also presumably interested in being her boyfriend -- to which Zoë says she's too young.

The note ends by saying that Noah must reread the note "500 times." If he does not abide by these rules, Zoë will not hesitate to let the adults in her life know.

Zoë's no-nonsense note has gone viral, garnering thousands of likes and retweets.

Hopefully, Zoë's note allows her to have a safe and fun school year.
