My son is a bookworm. He is addicted to reading. His favorite place to visit is a local library. He reads a lot. Every day he goes there to know something new. Every time my son takes different books from the library . He adore learning from his books that's why he does well at his school. All these books help him think more creative and develop his imagination.
When he's done with his books he returns them back to the library.
He really likes reading and I'm proud of him.
