Read the excerpt from chapter 6 of lizzie bright and the buckminster boy. "my granddaddy's been on that island since he was a baby," said lizzie, as quiet as the dark. "he won't leave. he'd never leave my grandmama. and he'd never leave my mama." "you won't have to leave. you can't have to leave." "that's what mr. tripp says. he's got this shotgun he waves around like ulysses s. grant, saying how he'll fight to protect our homes and such. he's about ready to declare independency." in the excerpt, what does turner not fully understand because he is a child?
