Facebook Quiet Hours
Facebook Quiet Hours are when the whole site is like a ghost town, and you're the only one there, probably because you're either crazy or you're still mad about that Farmville update from last night.
Status: 'I posted a picture of my dog and no one liked it. I think I'm dead.'
Tweet: 'My friend is online at 4 AM. I'm either impressed or I'm dying.'
DM: 'You're still online at 4:30 AM. Are you a ghost or just really stupid?'
