The loosening of the family bonds is one of the things which make modern life so unnatural, although the word "unnatural" is a very strange word. What is natural and what is unnatural? Natural is that to which we are accustomed; unnatural is that to which we are not accustomed. Sometimes centuries make something natural, sometimes a few years make a thing natural, and sometimes a few months. We call something natural because we are accustomed to see it as it is, but we do not realize that it has taken perhaps many centuries, many years, or many months to make it natural to us.
