I have it a bit different on FB I guess. I don't have anyone on my friend's list that posts shite that makes me cringe.
No old school friends that I never really liked.
Not my kids dad. Not my kids dad's family. I have an ex or two whom I parted ways with totally amicably and have no unresolved or lingering issues with.
My FB contacts consist only of people that I wouldn't mind having over for dinner.
I had way more at one point but their status updates made me want to stab myself in the eye with a spoon.
I did a huge clean up

And admittedly, when I or someone I know posts about a walk we/they went on, and how we saw the first signs of autumn or, share something we find meaningful, it is done in a genuine 'wanting to share with friends' and not just building a fake Visual of Who I Think I AM -- like so many do.
As for her comments and her response... yep it was like she was standin on her I'm SO Awesome pedestal.
