Singapore is a tiny island. It’s so small that one can hardly spot it on the world map. (Try it, if you don’t already know where Singapore is.) Because it is densely populated, consideration of others is especially important. A man wrote to his fiancée who was coming to Singapore for the first time: “Space is limited. Therefore . . . you must always have that sense of space around you. You should always step aside to ensure you are not blocking anyone. The key is to be considerate.”
