Charlie Pulp, 10, is so engrossed in her reading that she barely notices that Vinnie, a family friend has stopped by to say hello to her and her mom. This book is really intense, says Charlie. Its hard for me to tell you, Ill have to tell you the story so you can understand the moment. But Vinnie just laughs, making a joke about not learning much in school. All I know is E equals MC squared, and the speed of sound is 750 miles per hour, says Vinnie on his way out the door.
