Sloan Sayings

This weekend at Six Flags, Sloan was very concerned about the roller coasters. Our conversation went something like this:
Sloan: "That roller coaster is really high and goes super fast."
Me: "Yep. That's what roller coaster's do."
Sloan: "Is it scary?"
Me: "No, roller coasters are really fun."
Sloan (eyebrows raised): "Then why is everyone screaming?"
Me: "Uhhh...Those are happy screams because they're having so much fun."
I don't think he believed me...
