2. Fast transportation has made us all neighbors, but, unfortunately, not brothers.
Fast transportation is limited in number. Many people use them everyday, but they still feel uncomfortabe. In Seoul, too many people are in a place; a bus and subway at once. That's during the rush hour. People often argue. They want a space for themselves, but it's impossible and this situation occurs similarly with neighbors. We stay nearby, but we are far too close together.
Thank you!
