Many visitors to the United States find that the fast pace at which people move is very troubling. One's first impression is likely to be that everyone is in a rush. City people always seem to be hurrying to get where they are going. And they are very impatient if they are delayed even for a brief moment.
At first this may seem unfriendly to you: people will push past you as they walk along the street. You will miss smiles and brief conversations with people when you shop or dine in a restaurant. Do not think it is because Americans are in such a hurry that they are unfriendly.  Life is often much slower outside the big cities, which is true in other countries as well.
Americans who live in cities such as New York, Chicago, or Los Angeles, often think that everyone is equally in a hurry to get things done. But when they discover that you are a stranger, most Americans become quite kind and will take great care to help you.
