(Sheep are funny, the Whitlock said. Now, you look at how they behave when you throw some grub over the fence to them, such as corn stalks. Why, they'll spot that from a mile away. The Whitlock chuckled. They're smart when it comes to what concerns them. And maybe that helps us see what true smartness is; it isn't having read a lot of big books, or knowing long words...it's being able to spot what's to our advantage. It's got to be useful to be real smartness.)
