“Nothing! Look at your hands. And look at your mouth. What IS that truck?”
“I don’t know, aunt.”

The switch hovered in the air—the peril was desperate--
"My! Look behind you, aunt!"
(7)The old lady whirled round, and snatched her skirts out of danger. The lad fled on the instant, scrambled up the high board-fence, and disappeared over it.
His aunt Polly stood surprised a moment, and then broke into a gentle laugh.
(8)"Hang the boy, can't I never learn anything? Ain't he played me tricks enough like that for me to be looking out for him by this time? But old fools is the biggest fools there is.
