When I was in third grade, I suddenly stopped talking to my best friend for no reason. Later, I really didn't like this state, so I told the teacher to change my position and then drifted away. It wasn't until I went to college that we met at a party one day and started chatting, only to know that she might have called me, but I didn't hear it, and then nobody talked to anyone. That moment was funny and angry, and I felt that I had blocked my heart for so many years.
