Perhaps as you read this sentence, cars and trucks are passing by outside, a dog is barking, your roommate is playing the Limp Bizkit for the hundredth time - and all this goes on without your really noticing.
Really ought to be spell checked. My old word perfect used to have a grammar checker too, are those still around? Because it is really sad to read a paper with spelling and grammar errors all over when it is by people in the US. Also, I think the phrase "a novel approach" should be outlawed.
