city

I observed that too. Whenever I come home to my hometown, a lot of people would greet me and I wouldn't even know who they are. People know everyone else and are very friendly. People in the city are always on the go, lives a stressful life and worry a lot. People can't find time to notice the people around them like their neighbors because they are busy with their own lives. Sadly, we prefer to be alone and just be on the internet than exchanging chit chats with our neighbors.

just a few kilometers away from the city..

Large cities in the US have too much traffic and crime. I prefer the suburbs within driving range to the city if I want to come in for an event.
