We may spend a year in a town, and we may know people there and like them very much, and they may like us very much, so that the love increases and we think, "If we could only spend all our life there!" When we go away it is hard to leave them. Then we go away, and our friends send letters and we answer, first every day, then every week, then every month, until the correspondence is reduced to a Christmas card or New Year's greetings; for we grow apart by the fact that we have much less to do with them and much more to do with those who may now surround us. If we go back to the same place after five or six years we first find that the climate is strange to us, and then that neither are the streets and houses familiar nor is there that warmth in the friends that there was. If a person is ignorant he blames the friends; if he understands he will blame himself too. It is growing together that increases love and being separated that has the tendency to decrease it, and so it is with our attachment to places also.
