Facebook Hang up
Your friend is talking to you on Facebook and then just disappears. No warning. No sign-off. Just ‘poof.’ You're like ‘What the hell just happened?’ You're left thinking they either got run over or they're the laziest person on the planet.
You were telling them about your day when they just left.
You were about to tell a joke when they vanished.
You were in the middle of a rant when they disappeared.
