Facebook: what is it for? If you're a parent – especially a first-time one - bragging about your kids, right?
Not in Australia, it seems.
For one proud mum who shared the milestones of her baby Addy's life has been told to put a sock in it by her so-called friends.
Jade Ruthven, 33, a first-time mother from Perth, did what most people on Facebook do by writing about her everyday life.
And her life right now happens to be – understandably - focused on her baby girl.
But one of her friends (who needs enemies?) sent her an anonymous (predictably) letter telling Jade to 'give us all a break'.
The typed letter said she 'got together with a few of the girls and we are all SO OVER your running commentary of your life and every single thing Addy does'.
The letter says: "Look we all have kids that we are besotted with - guess what - every parent thinks their child is the best.
"But we don't ram it down everyone else's neck!!! She wears a new outfit - well take a photo and send it PRIVATELY to the person who gave it to her - not to everyone!!! She crawls off the mat - we DON'T care!!!!! She's 6 months old - BIG DEAL!!!"
The letter urges Jade to return to work so that she will not have as much time to spend on Facebook.
It adds: "Not everyone is as interested as you are about what Addy does so give us all a break.
"We're doing this to let you know what people really think."
Jade and her husband forwarded the letter to a local comedian, who shared it on social media and it quickly went viral.
Jade, a dental hygienist, said she was saddened by the 'nasty' letter but decided to publish it rather than give in and remove herself from Facebook.

She told Mail Online: "At first I was in shock and thought this letter must be a joke. I read it and reread it about four times.
"I was shaking with anger and shock to think a so called friend of mine could be so heartless and gutless to not even sign their name ...
"Being a first time mum is hard enough to get your head around but for someone who was feeling alone or who was struggling with the challenges of motherhood this could have had terrible consequences."
