I fell in a hole

Many years ago, I went to the mountain with my parents. That mountain was in the North of Portugal.
We were exploring the forest vegetation, everyone on its their own, and, suddenly, I fell in a deep hole which was in the ground. I started to shout, but my parents couldn't hear me.  Later, my parents realised that I had disappeared and they started looking for me. 
They told me that they couldn't find me, and that they were so nervous that they called the firefighters. Fortunately, the firefighters discovered the hole in which I had fell fallen, and they rescued me.
The story ended happily, because I could return home with my family. Now, when we go on a hike, I never separate from them.
