The cold breeze send chills to him. He decided to play some music so that he wouldn't be bore. He put his headphone and he start roaming in the melody music. But after sometime he feel someone's eyes on him and he look beside to see a man in a black set of clothes. Sanjay try to see that man's face but it was covered with a scarf. Sanjay was kind of get scared of that man's presence so he didn't want to make any conversation...but suddenly a wave of wind make his scraf slip from his face. It was a dull cold face with full of scratches and dry blood marks. It makes Sanjay scare the hell off. Before the man could make any move the bus arrived.
