If you've ever lived or worked with a passive-aggressive note-leaver, you'll know they can be some of the most irritating things in the universe to receive.
But one UK mother has discovered that sometimes a passive-aggressive note can be the funniest thing in the world - when they come from young children.
She was left in stitches after coming across the letter penned by her seven-year-old daughter, who was very unimpressed about being asked to switch off her Disney movie and get ready for bed.
Taking to Reddit, the woman shared a photo of the complaint, explaining: "Whenever our daughter disagrees with a parental decision, we receive these passive-aggressive cards."
On this occasion, the letter began: "To Mum, I see you want me to wash but I truly want to watch Moana so we can finish it and you will get to know how it ends.
"I should not tell you so you will be able to find out how it ends but I would not want to dispoint you so I will wash." [sic]
To illustrate her sadness, the girl had drawn two figures next to the letter, with one showing an unhappy face and a 'tick' beside it, the other showing a happy illustration, which had been scribbled out.
Other parents and amused Redditors quickly took to the comments to praise the creativity of the little girl's response, and muse on how it indicates a certain type of communication as an adult.
"Her email game is going to be fierce," one person pointed out.
"That's top-level emotional manipulation for a child. I'd be proud and scared," another advised.
"She will truly be a formidable housemate come university," another joked.
It's not the first passive-aggressive note from a kid to go viral.
Earlier this year, one mortified mum discovered her six-year-old daughter had been leaving instructions for their cleaner.
