Memorable Lesson

My memorable lesson.
  I grew up in the countryside which is covered by many rivers, and the small river behind my house was the one i liked most.

He knew that i really liked swimming and he was the only person who supported me to learn it, therefore in my birthday he gave me the buoy and hoped that it would help me to swim easier.
