A book is not just a collection of words, it is a perception portrayed on blank sheets. You know, getting you the feelings of blowing winds and rains and sun and flowers around, the smiles, the tears, the notional links with the characters and make them all alive, while you read. And that’s sure as hell a gruelling task !
People who think that grammar is just a collection of rules and restrictions are wrong. If you get to like it, grammar reveals the hidden meaning of history, hides disorder and abandonment, links things and brings opposites together. Grammar is a wonderful way of organising the world how you'd like it to be.
