When I was in primary school, I would find two other girls, one of whom lived near my home, and I would wait for her to go to school after dinner. I can't go home for dinner during the day in junior high school, so I won't wait for her. The competition between this girl and me was not obvious in primary school, because at that time, the competition was all fun, and there was no strong goal, only hard work.
In junior high school, because my sister's grades are good, I also want to be excellent. In junior high school, many students came in, so I met a group of friends who worked hard together. I didn't seem to think much about what I said then. But the older you get, the more you think, and the more cautious you become in making friends. Many times, friends will get tired of interpersonal relationships.
