I was on holiday in a strange place.One morning I got up early and went off into the forest looking for beautiful birds.But I lost my way,and don't know how to come back.I took a cell phone with me,but it didn't work there.It was night and I was frightened because I was alone and there were full of dangerous animals.I climbed up to a tree and was afraid of sleeping.Next morning I was tired.I thought what I should do to save myself.I tore my clothes into small pieces and tied them to the trees that I passed.At last my friend found me according to the pieces that I left.I was saved.That is an unforgettable experience in my life. Who saved the writer?
His father. His friend. His mother. None.
