Fabnesia
A sneaky way to avoid looking like a psycho who knows every little detail of your friend's life because they post too much.
'You don't know they got a new dog? I guess I'll just text them and say I know everything about their life.'
You didn't know your friend broke up with their mom? I guess I'll just say I'm not your friend anymore.
You didn't know your friend moved to Mars? I guess I'll just move to Mars with them.
