Silly me

There I was stuck in a tunnel with a beast roaring.The ambulance are on there way, however my legs are shaking, arms with goose bumps and stomach begging for food.Three hours have gone, no sign of any ambulances and praying for help, I took out my yellow phone and tried to find some signals but forgot about the beast.I saw the shadow then I hide behind the wall  but the shadow coming closer ,instead of the beast it was a dog that  howled like the beast it was remarkable,I discovered that the dog was the beast.
