If you think about this deeply enough (which I have because I find it such annoying, sad behaviour)
Most posting done on Facebook is pre planned for the desired reaction that you want or need.
I say most as I have a few friends that do post a lot. One lives in Abroad now and it’s all mundane type stuff but good to keep in contact with her close family and friends. The other posts all the time about family stuff but is from a huge extended family so it’s a way they share together and any other likes are probably not needed.
However most points are based around the need to show others that they don’t have a weakness in areas that they do.
Shitty Dads that get shit at home for not doing enough put photos of that one off #daddysdayout
People from poor backgrounds or an inferiority complex around money go for the luxury goods boasts and photos.
People in shitty relationships that make them feel insecure or who are in fear that they are not no.1 go for the #myworld type posts.
Girls getting messed around by men or are desperate to be noticed go for the constant tagging out and about plus numerous selfies.
Its so easy to flip it and see the truth!
Tagging out all the time - sits lonley on the sofa for the rest of the time.
Mum taking photos everywhere and making memories- feels guilty because she’s not coping and probably isn’t giving them the attention they need the other 90% of the time.
I can read Facebook like a book! Of course I have my own insecurities and problems but If there was just one person who worked them out via Facebook that would be too many. The shame!
