I believe that everyone will have something they regret in this life. Before doing anything, you must think carefully about whether you should do it or not, whether you will regret last night, family, love, making friends, or even eating. Or go to work, or even more, whether you should go out today, whether someone will be sad after doing these things, whether you will regret it, or whether you will be sad.
