Just record what I have encountered in my life. Recalling the time spent with friends can also be said to be "revisiting old things".
I am afraid that these days will soon be forgotten, so while I still remember them, I will write down some and encourage each other. Although it is unremarkable, it is extremely precious to me. A person will meet many people in his life, but when he looks back on the past, he finds that the time he spent with these people was the happiest.
I don't know how you feel about it, but just like a person drinking water, he knows whether it is warm or cold. Sufficient.
