I believe that every word you say and everything you do will inadvertently have a chemical reaction on your surroundings and leave traces on you for a long time.
Maybe one day in the future you won't remember what happened between you, the content of the chat, why you were so in tune with each other at the beginning, or why you had a dispute at that time, but you can clearly remember the mood at that time, whether it was happiness or sadness.
You remember those ignorant selves, and you also remember the excellent selves. You remember those helpless selves, and you also remember the brave selves. You remember those who hurt you, and you remember those who loved you.
Concept: What young people fear most is the word "future"
