Last One For the Day in Book Seven: Reconstruction 2020

I decided after everything today, I was going to be kind to myself. Just… turn off the outside world… play with my dog, do laundry. The other stuff on my to do list can be taken care of tomorrow. I worked my butt off last night at home and all day at the office today.

But then? I was stupid. And checked my phone. UGH.

Okay, so an etiquette question for you. AITA, if you will.

A friend whose FB privacy settings are ridiculously high (nothing on her page can be shared ever) said something I agreed with. It was not novel nor signature nor unique. It inspired me to write something. If I may illustrate the point vaguely… her post would be
1,2,3,4,5,6,7,8,9
My post was A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,6,9.

She is now upset with me for “copy and pasting (her) ideas and passing them off as (my) own.”

Where my AITA comes in is… if she does not want her content shared, and I used her ideas as part of a much larger post covering general reactionary hypocrisy… am I a shit for (1) incorporating her idea into mine; (2) not giving her credit for the two sentences out of 25 that were not STRICTLY my own; (3) or is it more appropriate to say “It was a generic statement on bloody Facebook, get over it!”?
