Educated Guessing

FavoriteBoy: Hey babe, don't you think you should call your doctor, since you've taken all the antibiotics she gave you and your ear infection is still bothering you?

SarahMarie: No, I think it's better. My ear hurts a little, but it'll probably take some time for the fluid to go away even if the infection is gone.

FavoriteBoy: What makes you say that? Are you sure?

SarahMarie (smugly): Educated guess.

FavoriteBoy: Educated by what?

SarahMarie: Hey, I'm educated!

FavoriteBoy: An "educated guess" doesn't mean a random guess made by an educated person, dear.
