While I was swimming,the sea became very rough and I tried to swim to shore.The harder I swam,the more I was carried out to sea.I was very frightened because I didn't know how to get to the shore.Suddenly a strong hand took my arm and pulled me into the shore.The stranger swam away and I never saw his face.I was sorry that I wasn't able to thank him or her,the person who saved my life.
