"What did you just say?"
"Nothing. Just had a little Feedjà vu."
"What did you see?"
"I scrolled past a picture of a cat, and then another that looked just like it."
"How much like it? Was it the same cat?"
"It might have been. I'm not sure."
"What is it?"
"Feedjà vu is usually a glitch in facebook. It happens when they change something."
