“ It is not always easy to do and say what is absolutely correct when one is in a strange country among people who speak a strange language. But he who is kind and courteous at all times, who has a ready smile and a polished manner, will avoid much of the embarrassment that awaits the tourist who is indifferent and careless. The proverb, "All doors open to courtesy," is as true in France and England as it is in America. ”
