Ohhh thats a classic 
"Just got some terrible news"
"Whats up mate?"
"Sorry i dont wanna talk about it"
f*ck OFF!!!!!!!!!!!!!!!! 
Yes mate that is annoying.
I never had a facebook until like December last year.
It's a very easy way of keeping in touch with your friends/family and sharing photographs etc.
It's only as drama-filled as you want it to be. I have no drama on mine, it's all banter and enjoying catching up with mates I'd otherwise never really talk to.
