When I look through my past space or circle of friends, I can always remember my feelings and feelings at that time. Although the mood may not be so strong, there will still be some fluctuations in my heart. For me, I am a particularly nostalgic and sensitive person. Happy things don't always make me remember a lot. On the contrary, sad things always make me unforgettable. This may be just that sentence, everyone's happiness is the same. And everyone's sadness is one in a hundred. For emotional people, the output of emotions may be expression. QQ space WeChat circle is a place for emotional expression. I am a person who seldom makes dynamic changes. Only when I am unhappy and uncomfortable, and there is no one around me to talk to, will I express my feelings in words, and will not seek comfort and care from others in my own mood. So, I send it in a form that only I can see. For me, it's just a memorial, a reminder that I still have some time. Of course, expression is a kind of catharsis, just like some people will write their happy and unhappy things in their diaries. I remember when I was in high school, I wrote down my mood swings every time. Whether I was happy or unhappy, the moment I wrote it appeared. When I am happy, my handwriting is neat and smooth. Like running water, when I am unhappy, my handwriting is scrawled. After graduating from college, I write my mood in my own space. I think my mood is my own business and a kind of privacy, so it is also worth protecting. It is set to be visible only to myself. Whenever recalling the past, there are different emotions in different periods. At that time, the mood can no longer be compared with now, and I can't feel the same, but there will always be some ripples in my mood. The dusty memories will eventually be turned over, just like an old movie, and you will still feel different every time you watch it. I think this is also the reason why everyone is willing to express it and stay. People will leave some memories before they get used to life.
