She Was RIGHT THERE a Minute Ago

SHREEEEEEEEEEEEEEE SHREEEEEEEEEEEEEEEE!!!!
"WHAT is that noise?" asked Shauna. SHREEEEEEEEEEEEEEEEEEEE SHREEEEEEEEEEEEE!!!
Kim, from her seat in the front of the canoe, said through her gales of laughter, "It's Judy. She musta woke up and found us missing from the truck so she is blowing her emergency whistle to alert us. Or somebody." "Emergency whistle? What is that?" asked Doris.
SHREEEEEEEEEEEEEEEEEE SHREEEEEEEEEEEEEEEEE!!! "Wait a minute, HOOTY HOOT, HOOTY HOOT!! There that will let her know we are close by. Anyway, years ago when we first started camping out, Judy passed out whistles to everybody with instructions to use them whenever we were in danger. This is the first time I remember anyone using one." "I didn't see any whistle around her neck," said Doris. "The bag," said Shauna, "She must have had it in her bag." As the girls talked they were making their way back to shore, Kim and Shauna in one canoe while Doris piloted the second canoe. "That was kind of a nice voyage, wasn't it? The water is calm and the moon shining through the trees makes you feel all calm inside," mused Kim. "I still think we shoulda had a race,.I coulda taken you two - easy. Woulda been like taking candy from a baby," answered Doris. "Well," said Shauna from the back of the canoe, "I still feel kind of guilty about leaving Judy alone in the truck." "It's not our fault she falls asleep at the crack of 9. I thought that gallon of iced tea she drank at dinner would surely keep her going," said Kim. "Land Ahoy," said Doris as she beached her canoe then reached to help with Kim and Shauna's. "Judy, hey Judy!" Kim shouted. No answer. "Quit joking around. We know you're here," Kim continued. Still no answer. "Maybe she got back in the truck and fell asleep. It's been 4 minutes since she was blowing that whistle," said Shauna. The girls approached the truck warily. Just as Kim reached to grab the handle there was the faint sound of shreeeeeeeeeeeeeeeeeeeeeeeeeeee from somewhere in the woods, followed by a thumping from under the truck cap on the bed of the truck. Squeals and shouts and much hustling and grabbing of door handles followed. It was useless. The truck cab was locked!!! And Judy was nowhere to be seen.
