Laura and Catherine moped the entire drive. They didn’t want to campout. They didn’t want to sleep in a tent, or eat roots of lilies and drink dirty water from a stream. They didn’t want to run into any scary animals, but most of, they didn’t want to sleep in the dirt. All they wanted was to be home in their nice warm beds, with no bugs, wild animals, or dirt.
Their mum and dad often went camping by themselves but this time they decided to have a family camping trip. «Mum, you know we don’t like to camp out!» Laura whined, but here they were, walking along a mountain trail, brushing twigs and leaves out of their hair every chance they got. Earlier they crossed a river and now their socks and shoes dripped with water and squished with every step.
At last they stopped for the night. Dad set up the tents. «Girls, go and gather some firewood so Mum can start supper. I’m starving.»
«I hate camping!» Catherine complained, as she and Laura picked up dead branches from the ground.
Laura dropped the gathered bits of wood on the ground. «What’s for supper?» she asked. «Where’s Dad?»
«He’s off catching supper for us,» Mum replied.
«What is he catching? Butterflies? Lizards? Fish?» She saw the look on her mum’s face. «Fish? We have to eat fish?» Catherine griped.
«I brought some snacks in my backpack, but yes, we’re eating fish for supper,» Mum growled. She was getting fed up with the girl’s constant complaints.
Dad appeared an hour later. A roaring fire popped and sent fiery embers into the air. «Get the frying pan ready, Mum. The fish were biting tonight.» The girls watched in horror as he gutted the fish, cut off their heads and tails and threw them onto a heavy black pan. They sizzled away, sending fishy-scented smoke into the night air.
«I’m not eating that!» Catherine said. «You cut its head off. What if you didn’t get all the guts out? That’s disgusting!»
«Don’t be silly, Catherine. Of course it’s clean. If you don’t eat the fish, you’ll have to go to bed hungry,» Mum warned.
Reluctantly the girls ate the fish. They enjoyed it much more than they let on.
Laura and Catherine went down to the stream and washed the fish scales and tinned beans off their faces and hands. They went back to their tent, pulled their wet shoes and socks off, and put on their soft, clean pajamas.
Mum and Dad made up their beds in the dirt. «Aren’t you sleeping in your tent?» Laura asked.
«No. We want to be out in nature,» Mum answered.
«I’m glad we don’t have to sleep in the dirt,» Laura said. She lay down in her sleeping bag next to Catherine. «They’ll get eaten alive by midges and mosquitoes.»
Catherine tossed and turned. «Mum, there’s a rock poking into me,» she whined.
«Mum, there’s something tickling my nose. What if it’s a spider?» Laura feared.
Dad removed the rock from below Laura’s blanket and Mum checked Laura’s bag for spiders. The girls were told to get to sleep right away, which is what they did, at least for a while.
«What’s that noise?» Laura asked, shaking her sister awake. They sat up and listened. Clouds moved across the moon, making it look rather spooky.
HOO! HOO! HOO!
«What was that?» Catherine asked, pulling the blanket up around her neck.
«I don’t know,» Laura answered.
HOO! HOO! HOO!
«EEEEEEEEEEEEEEEEEE!» screamed the two girls. «EEEEEEEEEEEEEEE!»
Mum and Dad jumped up from their bedrolls. Dad bumped his head on a low hanging branch of a tree. «What is it girls? What’s the matter?» he asked.
«There’s a ghost hiding in that rowan tree over there!» screamed Laura.
«It’s a monster!» cried Catherine.
HOO! HOO! HOO!
Dad laughed. «It’s only an owl girls. An owl is a bird and that is the noise it makes at night. It won’t hurt you, I promise. Now go back to sleep, please!»
Mum got up and tucked the blankets around them. They fell back to sleep quickly.
CROAK! CROAK! CROAK!
«EEEEEEEEEEEEEEEEEEE!» screamed the girls.
