I think no matter what, every friendship is an indelible memory in my heart, but it's hard for me to go back, because the feeling of friendship has a lot to do with time or you at that time, so I don't regret it, because the friends who are still with me now are the people I need to cherish most, the people who know me best and the people who can sing with me best. They may just leave because there is no fate, or their future life.
Take friends at every stage of life seriously, so that even if it is over, there will be no regrets. Regret may be just because I missed it, or I should have done better at that time, and maybe I could have saved this friendship. But how can you be who you are now?
