Once I saw someone I knew retweeted an article about a short space sentiment written to a stranger, and I immediately felt very moved. In this complicated society, changes in lifestyle, increase in speed, and changes in attitudes have all changed us. Sometimes we will talk about many things we encounter, happy, sad, happy, painful, but the person we talk to may no longer be the people in our familiar life circle. Because we don't know each other, we may be more open-minded, and because we have no scruples, we can complain more. When we face people we are close to, we are more reticent, but on the contrary, we are more willing to communicate with "friends" on the Internet. Therefore, when facing "strangers", I prefer to believe that they are all kind friends in life.
