Nowadays, many people who live in big cities do not know their neighbours very well. This is becoming a common problem because people are busy with their work and personal life. This situation can cause some problems, but there are some ways to solve it.
One problem is that people can feel lonely and they do not have someone near them to help. If people do not know their neighbours, they may not ask for help when they have a problem. Another problem is that people can be less friendly and they do not communicate with other people in their area. For example, if a person has a problem at home, they may not know who they can ask for help.
There are some things that can be done to solve this problem. First, people can spend more time outside and talk with their neighbours. They can also have small events in their buildings or local areas. For example, neighbours can have a meeting or a small party together. Also, local governments can create more places where people can meet and communicate with each other.
In conclusion, not knowing neighbours can make people feel lonely and less connected with people around them. I think people and local governments should create more opportunities for neighbours to meet and communicate.
