New York is always changing. You can hear it all the time. Cars and buses stop and start and policemen blow whistles at the drivers, people run between the streets and avenues. That's New York. That's one of the most wonderful cities in the world.
Is New York dangerous? Perhaps it is, but many big cities are dangerous. Remember:
don't have a lot of money with you;
don't travel on the metro alone at night;
stay with people late at night;
go into the nearest hotel or shop if you suddenly feel afraid.
When you are going to visit New York, remember that the city can be very hot in summer and very cold in the middle of winter. Go at the right time and take the right things with you.
Some visitors find that New York and New Yorkers are not very friendly. Well, some are, some are not. Some taxi drivers talk during the trip, some talk if you talk to them, but only to say "Yeah" or "OK!"
