One: Some people just don't like this atmosphere.
Maybe everyone's new songs are different. Some people like to be lively, but some people don't like this lively atmosphere and prefer a quiet life. I feel that I may be more free alone. You can eat alone, go shopping alone, or you can be very happy. Not introverted, just like quiet, if there are many people, it will make people more annoyed. So I don't want to take part in some group activities.
Two: Enjoy the time alone.
In today's society, there is really too little time to be alone. Many times we are constantly working or studying, but forget to sit quietly and enjoy some alone time. So when you have a little time, you will stay in your own world, or empty yourself, or do something you want. In short, in a noisy society, time alone is more precious.
Three: Everyone was playing with their mobile phones when we went.
Now the parties seem to be all one person. Although everyone said they were all sitting together, they were all playing with their mobile phones. This is the furthest distance in the world, and it won't be like before, when everyone just sits and plays together or sings. The nature of the party has changed, just playing mobile phones in another place, and everyone is too lazy to go.
Now the pace of life is really too fast, so fast that we are all caught off guard and can only run as hard as we can, so we all want to be alone while we have time.
