Here's an example:
People get excited about how many 'friends' they have, but are they friends....not really.
People all have perfect lives on FB, great holdiays, great jobs, new cars, stunning partners, loads of money, false economy.
No one is ever a crack addict or has a low paying menial job, ugly partner etc etc.
It's totally plastic and fake - not for me.
Based on some of the replies on here tho, many people love it.
Oh, and one of my favorites it hear a lot of people say 'i never post anything' - comedy gold.
