I wonder why American towns look so much alike that I sometimes mix them up in my memory. The standard influence (影响) of mass production whose agents (代理商) are the travelling salesman, the mail-order house, the five-and-ten-cent stores, the chain stores, the movies can hardly explain it. If you stay two days in Bologna and in Ferrare, or in Aries and in Avignon, you will never mix them up in all your life. But it may well happen that after you spend two days in St. Louis and in Kansas City the appearances of these two cities soon mix up. I think the reason for this is that these towns have not yet had time enough to develop their own characters. Similarly, children are much less different from each other than grown people.
