A five-year-old girl wrote a hilarious Christmas card to a teacher at her school accusing him of "blaming his farts on students".

Mum Sally Parkes, 44, asked her daughters to write some Christmas cards whilst they wound down for bed one evening.

She set up her children Rosalie, five, and Bonnie, nine, with some pens, cards and envelopes and let them write notes to all their favourite teachers.

Rosalie had been sounding out her sentences when Sally overheard her saying ‘farts’ and ran to investigate.

The video captures Rosalie innocently reading what she was writing: "You blame your farts on the children at school", much to mum Sally's shock.

Sally, a yoga teacher and author, can be heard bursting into laughter, while older sister Bonnie is heard telling Rosalie that it's "rude" to write that in a Christmas card.

“We are quite open about bodily functions and anatomy, so that’s why she didn’t get why it was awkward at first," said Sally, from Worthing, West Sussex.

“She was quite confused and you can see her trying to work it out, but she did get it in the end.

“I didn’t know this at the time, but earlier Bonnie had told Rosalie that her teacher blamed their farts on the children.

“She was trying really hard to put extra information in the cards - telling teachers that she loved them - so I think that’s what she was trying to do here!”

Sally uploaded the clip to her Instagram account - @sallyparkeswomensyoga - where it has since amassed over two millions views.

She added: “I put the video up and expected maybe 50 likes at most, but now it’s at over two million. It’s crazy!

“We haven’t sent the card, but I might do now. My partner is a teacher and confirmed that this is definitely a thing teachers do!”
