A Glimpse of New York

2004 April, I went to USA. I stayed in Orlando and New York city for a couple of days. Once I wanted to go out from the hotel in NY, I always took subway all the time. But every time I enteried the carriage, I usually felt weird automosphere mixed with coldness and precariousness full of the whole carriage. Some people went in and some people went out when the subway stopped. Most of them just put on their headphone and looked like a dumb. I couldn't help thinking if I fell into coma suddently, would the passenger sitted next to me help.
