A Strange Guy in Skytrain

One day, I wanted to go to Down Town, so I took Skyrrain. First, there was nothing serious, however, one guy came. He looks so dirty, but that was ok, I did not care. Actually, he said something to another guy, that guy ignored him, so he was a little angry. Then, he was spitting on the Skytrain’s window and speaked by himself. The most terrible was that he always counted his fingers, again and again. In addition, I think he is so poor, nobody want to talk with him, including me. While, his abnormal behavior gave me a big fright.
