why do girls well the one's i know post so much stupid posts on facebook seriously why?

[User]

So i'm amazed by the stuff this girl's post on facebook. Since the holidays here nearing an end,they've been posting stupid statuses like their gonna die if they go to school and why does school even exist(a/n:this girls have a big social circle i mean like thousands of facebook friends,attention whores?)

Not only that,i want to also know why some girls post a lot of love related statuses,this also goes for the guys why? If you love someone that much stop sitting on your ass and go out and talk to them sheesh ! (a/n:sorry 'bout that i just need to get that of my mind,its baffling me.)
caramel i don't think they want to admit it themselves,plus their too busy updating their statuses every few minutes or so
