Hilarious! Little girl's "brake up" letter is going viral!

MILWAUKEE (WITI) -- Oh man! One little girl has had enough of her "boyfriend!"

In a letter that's going viral, she accuses the boy of not speaking to her since the "day he asked her out" -- three months ago!

She ends her letter with a thoughtful piece of advice about marriage.

The note was posted to the Instagram account of a man named David Demarest. He says he found it "on a website."

It’s a little bit suspicious -- especially as any questions about exactly where the note was found haven’t been answered yet.

Real or not, the advice that Shawn should ‘git it together’ is something we can all take on board.
