We admit, we often grow tired and frustrated of that bragging friend on Facebook but we would never dare say anything. However, this group did.
An unknown number of disgruntled Facebook users in Australia wrote an anonymous letter to their friend, new mum Jade, after she posted frequent updates of her baby daughter Addison on the social network.
"We are all so over your running commentary of your life and every single thing Addy does," the candid note begins. "Look we all have kids that we are besotted with - guess what - every parents thinks their kid is the best ever. But we don't ram it down everyone else's neck"
"She wears a new outfit - well take a photo and send it to her privately to the person who gave it to her - not to everyone"
"Stop and think - if every mother posted all that crap about their kid - I'm sure you'd get over it pretty quickly," continued the grating letter. "Addy is gorgeous and we all love her, but our kids are great too...We're doing this to let you know what people really think."
Shocked by the letter, Jade, 33, sent it to Australian comedian and writer Em Rusciano, who then shared it with her thousands of followers on Facebook yesterday.
"My initial reaction was: “That is some Lindsay Lohan, Mean Girls, burn book, on Wednesdays we only wear pink bull****," wrote Rusciano on News.com.au.
"Although before we get all high and mighty I’m sure that most of us have been guilty of some light fitching (Facebook b*******) from time to time...You best believe that I’ve engaged in some serious eye rolling, to claim anything else would be untrue."
"Although...there is a way to have a gentle conversation with someone you feel is overstepping the mark on social media that doesn’t cut them off at the knees...It attacked her mothering, her self-perspective and probably left her feeling as though all her friends had turned on her," added Rusciano.
Jade has since spoken about the letter to Daily Mail Australia, saying: "At first I was in shock and thought this letter must be a joke. I read it and re-read it about four times."
"I was shaking with anger and shock to think a so call friend of mine could be so heartless and gutless to not even sign their name," she added. "To be honest I have no idea why anyone would do this to me. I don’t think I have had an enemy in my whole life."
Messages of support are pouring in on the mother's Facebook page. One user wrote, "I would love to watch the wonderful progress of your new baby" while another added "Whatever you post on your page is your own business."
