About 1 A.M. at the crossroad of 33rd street and 7th avenue , Manhattan .
New York is a sleepless city . Many people are hanging around all through the night .
Even three in the morning I saw some people played an electric organ in the street .
London and Paris and some big cities are also sleepless , but I think New York is the busiest city around the clock and also noisiest . In 2014 I stayed there for about 10 days , and everyday somebody shouted somewhere in that highly crammed city .
