For whatever reason, there are people we like and people we don't like. It's hard to say why, and often a difficult opinion to change. Luckily, there's no steadfast rule stating that we must like everyone. But to keep from disliking ourselves, we should develop the good character to treat everyone kindly, whether or not we deem them deserving.
Cities were always like people, showing their varying personalities to the traveler. Depending on the city and on the traveler, there might begin a mutual love, or dislike, friendship, or enmity. Where one city will rise a certain individual to glory, it will destroy another who is not suited to its personality. Only through travel can we know where we belong or not, where we are loved and where we are rejected.
