The best gift for anyone, albeit; children or adults are books. Reading books not only enhances knowledge but improves vocabulary and grammar manifold! Reading other than text books is one of the best gifts for ourselves. As the 23rd of April is celebrated as World Book Day and English Language Day, it couldn't get better than this.
English is the language of the world and it's quite imperative to speak, write and read in good measure. One can survive anywhere in the world if they know how to speak English.
There are many age appropriate books for everyone. A friendly neighborhood library or similar must be easily accessible. It's a simple joy in life to curl on your favourite couch and get lost in the reams of a story book.
Like-minded people can form a reading club and exchange books quite often. By this, the community of readers gets expanded. Once a week or a fortnight, reading marathons can be organised in local clubs or libraries where children and people just sit back and enjoy what they read.
Gifting good reads is also a great example that can inculcate reading habits in children, and wean them away from unwanted media. If you don't have the habit of reading books, then, this is the right day to start one. Go, grab a best seller. Let the reading begin..
