Parveen Sharma is a writer/defence builder. As his father was in the defense services, he was subjected to a lot of transfers. This gave him the chance to be in many new cities and new schools. Every place had its own unique story and every school had a different environment. But everywhere, the playful children and the crazy mischief of childhood were common, which is why the author advises people to become a child again. "Don't be shy. Be childish!"
