“There’s a pirate asleep in the pampas just beneath us,” Peter told him. “If you like, we’ll go down and kill him.”
“I don’t see him,” John said after a long pause.
“I do.”
“Suppose,” John said, a little huskily, “he were to wake up.”’
Peter spoke indignantly. “You don’t think I would kill him while he was sleeping! I would wake him first, and then kill him. That’s the way I always do.”J. M. Barrie (1860-1937) Scottish novelist and dramatist [James Matthew Barrie]
