write a short narrative about an accident you have or seen... ( help me please )♡★○

Yesterday, on my way home from school I saw a horrible accident.  The roads were wet.  There was a car driving down the hill too fast.  Suddenly, a little dog ran into the road.  The car swerved and tried to avoid the dog.  But, unfortunately, he ran right over the dog's owner.  The man looked like a pancake.  There was blood everywhere, but no dog.  It was a terrifying experience.
