First of all, we have chosen different paths, which are doomed to drift away. If we all choose to go to school, then we may be in the same school. Even if we are not in the same school, our relationship will certainly not break down. On the contrary, our relationship will only get better and better, because we have a lot of common topics and experiences when we choose the same road, and our relationship will get closer and closer when we are already familiar with it. But we chose different paths, so we didn't know each other's situation and didn't know what to say when chatting. Slowly, our relationship broke down.
Secondly, some of my former friends can't continue to go to school because of poor study, and may feel inferior or don't need to keep in touch with us to continue to go to school, so they gradually alienate us. They will think that going to school and not going to school are people at different levels, and there is no need to keep in touch. In fact, this idea is not good, so everyone is equal and no one knows who will succeed in the future. However, friends should not be separated by different paths.
Finally, we don't get along well with each other. Everyone is busy with their studies and careers, and there is little time to meet or chat. In the end, there is little or no contact between the two sides, which is really inappropriate.
