" The concept of darkness. A very vital yet disastrous occurrence to life. A force which contends with light at all times, taking its dominance towards the appearance of dusk. A time when nature shows its other wonders. This darkness, sometimes resides in places with abundance of light. Hidden amongst us! what matters mostly is the ability to tell its presence apart. As many tend to be lost in their darkness, not owning up to seeing the light which has always laid before them. "

Old man Elvis stood firmly at the front of the class room, giving out his lecture in his somewhat hoarse tone of voice. Despite his withered looks, he was able to gain control of the entire class after showing a demonstration of his profundity.
