People who check into the local hospital, make some comment about how they are here again and then once everyone has posted thoughtful comments, say "everything's ok, just the usual 3 month check up" or don't respond at all.
People who put a feel sorry for me status like how awful the day has been and how people can be so awful then just say it's just one of those days when countless people ask, day they'll pm you or say "yeah I'm ok, you?"
People who post photos of what their partner got them for valentine's Day and how loved they feel. Loads of presents don't been loved, its called being spoilt and the only reason these photos are put up is to show off to everyone. The same goes for birthdays and Christmas.
People who post photos of a weekend away and when you try to start a conversation about it they ask if you saw the photos online? "No I want an actual conversation and I got bored of looking at 150 plus photos of the local wildlife park so didn't finish going through them!"
My brother in law's ex girlfriend used to post selfies of her in the bathroom mirror, fully made up and hair done, pouting at the camera "just popping to the shops" no, you want everyone to tell you how beautiful you are.
People who put so many photos of their night out, you wandered if they've spent the whole time just taking photos and then posting them on Facebook.
One girl I have on Facebook puts a running commentary of what's she's doing, usually about going out running, going to a fitness class, working, looking after her daughter and what skimming world food she has. She then gives us a weekly update on her weight loss.
It's all attention seeking.
